Antenna is an important part of all radio communication and detection systems. From the single point-to-point wireless communication at the beginning of the century to the GPS satellite communication system covering the whole world at the end of the century, antenna technology has undoubtedly assumed the most basic and cutting-edge role. At present, various products of antenna combined with microwave technology are everywhere, and its influence is from people's daily life to national security, so its importance is self-evident. We have strong research strength in antenna theory and technology. With the efforts of Professor Ren Lang, an internationally renowned antenna expert, for decades, 27 doctoral students and 4 postdoctoral students have been trained in this research direction. Now it has developed into a dynamic research direction with complete research echelon, fruitful research results and complete experimental equipment, and its academic status is in the leading ranks in China.
The research contents and features in this direction include: (1) antenna theory and antenna analysis method. Closely follow the latest research trends and achievements in the international antenna field, constantly develop and improve antenna theory and antenna analysis methods, and constantly publish high-level academic papers, which has aroused widespread concern in academic circles at home and abroad. (2) Waveguide slot phased array antenna. Because of its compact structure, easy control and phased array technology, waveguide narrow-side slot planar phased array antenna can quickly capture communication satellite signals. Based on this, the automatic tracking synchronous communication satellite TV receiving system has been successfully applied to trains, cars and other moving objects, reaching the domestic initiative and international leading level. (3) Optimization theory of antenna and antenna array. The content includes the optimization of bending dipole, broadband bending dipole and bending slot antenna, as well as the dual optimization of bending line dipole element and variable curve array. (4) Research on dielectric resonant antenna and antenna integration. In millimeter wave band, the development of microwave integration makes it possible to integrate antenna, source, microwave device and intelligent system on one chip, thus forming a monolithic integrated intelligent communication system. Therefore, the metal-free dielectric resonant antenna has become the main integrated antenna form. This is also one of the main characteristics of this research direction. (5) Research on microstrip antenna. Including the research of stacked microstrip antenna and its back cavity microstrip antenna, the analysis method of microstrip antenna has been improved and developed, which has attracted the full attention of international academic circles in recent years.
So far, we have made some achievements in the above direction. Among them, in the research direction of optimization theory and technology, we have made some achievements in the optimization of low sidelobe optimal bending antenna array, and the related national natural science foundation projects and Sino-German international cooperation projects have also been successfully completed. Peer experts believe that these achievements have reached the international advanced level.
At present, the National Natural Science Foundation's key project "Automatic Tracking Synchronous Communication Satellite Planar Phased Antenna Array" has been completed. One of the main problems we study is that the system can automatically track and receive the signals of synchronous communication satellites when moving anywhere in China, and the radiation pattern has no grating lobes and the beam remains stable. The high-quality completion of this project can not only further improve the academic level and status of this research direction, but also quickly realize the transformation of scientific research results into high-tech products, which will directly play a role in the national economic construction and national defense equipment construction.

This research direction is the fastest developing and most dynamic field in modern electromagnetism, and now it has become an important branch of electromagnetic field and microwave technology. With the problems involved in the application of modern electromagnetic field engineering becoming more and more complicated, and the electrical size becoming larger and larger, the role of computational electromagnetics becomes more and more important. Its specific applications cover many fields of engineering electromagnetic problems, such as electromagnetic stealth and anti-stealth, microstrip antenna analysis, microwave circuit design, human electromagnetic dosimetry, microwave antenna design, microwave remote sensing and so on. Its military and economic application prospects are quite broad. Our main research contents include the following aspects: (1) the application of Thompson transform in the field of fluid mechanics in electromagnetic calculation, and the numerical solution of practical complex electromagnetic problems under the precise matching of body-fitted coordinate system. (2) The research on real-time calculation method of radar cross section of complex targets related to stealth and anti-stealth technology not only provides a very useful and convenient analysis tool for target designers, but also lays a foundation for real-time detection and real-time response of targets. (3) Study on transient electromagnetic response in time domain. (4) Study on the interaction between chiral composite media and electromagnetic signals.
The numerical methods we use not only cover the three mainstream methods, such as finite difference time domain method, finite element method and moment method, but also introduce and develop new ideas and methods from other fields and disciplines, and conduct interdisciplinary research, such as differential transformation, fractal theory, genetic algorithm, neural network, wavelet transform and Born method. In this direction of scientific research work, gradually formed its own characteristics. For example, the application of fractal geometry in electromagnetic field and the research on real-time algorithm of radar cross section of complex targets started earlier and are in a leading position in China. The application of fractal geometry in electromagnetic field is very promising, because the exact solution of Maxwell equation or wave equation is greatly limited by the integer coordinate system. The application of fractal geometry may make many practical electromagnetic problems get strict solutions, greatly expanding the scope of possible solutions. In the real-time calculation of radar cross section of complex targets, on the one hand, T-FDTD method can be used to solve the electromagnetic scattering characteristics of complex structural targets, which provides theoretical basis for the design of electromagnetic stealth and anti-stealth materials and their geometric shapes; On the other hand, SBR technology with superior performance can solve a series of problems such as shortening the judgment time of occlusion factor, simplifying the calculation formula of scattering field and determining creeping wave, which makes real-time calculation possible.
Stealth and anti-stealth technology play a very important role in national defense research. In a sense, it reflects the level of a country's computing equipment and means. In this respect, our main research field has involved or will involve several issues: (1) Using efficient numerical methods to analyze the influence of target shape and material on radar cross section distribution. (2) Using genetic algorithm to optimize the distribution of layered absorption media to obtain the best stealth effect. (3) The related problems of pulse radar and anti-stealth are studied by using hybrid numerical algorithm.
The generation, scattering, pickup, shielding and simulation of pulsed electromagnetic fields pose many theoretical and computational problems. For example, the target characteristics of aircraft and missiles, the target scattering characteristics of electromagnetic detection technology, and the coupling of holes. In order to solve these problems, we separate the incident wave from each reflected wave in time, and propose a method of' solving in turn' in time to solve the above problems. The advantage of this method is that it can improve the calculation accuracy, simplify the problem and solve it easily. The proposal of this method has had a great influence on peers at home and abroad. At the same time, the narrow pulse problem actually corresponds to nanosecond technology, which plays a very important role in the design and packaging of VLSI. Historical evolution of curriculum development
Southwest Jiaotong University, founded in 1896, is one of the oldest institutions of higher learning in China with a strong historical accumulation. The school has always attached importance to the teaching of basic courses, forming a fine tradition of "rigorous scholarship and strict requirements".
College Physics is an important basic course for science, engineering, management and liberal arts majors in our school. It is one of the first batch of key courses and first-class courses of the Ministry of Railways in our school, and it is also one of the first batch of excellent courses built in our school. In 2004, it was rated as an excellent course in Sichuan Province. The course of teaching reform can be roughly divided into three stages:
The main reform idea in the first stage is to carry out "all-round" physics teaching activities based on quality education. Try to expand the influence of physics on students. During this period, college physics was rated as an excellent course of the Ministry of Railways and a first-class course at the school level, and also achieved excellent results in the unified examination of college physics in Sichuan Province, which was commended and encouraged.
The main feature of the second stage is that, by hosting and participating in educational reform projects at all levels and combining with the reality of our school, the physics course "the reform of teaching content and curriculum system for 2 1 century" has been carried out. Introduction to Physics, compiled and published in this period, is one of the earliest reform textbooks in China, and won the second prize of 1998 for scientific and technological progress of the Ministry of Education. The teaching reform achievement of this course "Facing 2 1 century and systematically reforming the engineering physics course" won the first prize of Sichuan Excellent Teaching Achievement in September, 1997.
The third stage is: on the basis of the reform of teaching content and curriculum system, supporting reforms are carried out in teaching practice, including the reform of teaching methods and means, the reform of examination methods and the reform of students' comprehensive assessment. The modern teaching methods based on multimedia technology and network technology have been extensively studied, and the developed CAI courseware, electronic teaching plan and network learning system have won the first prize of national computer multimedia and network physics teaching achievements for many times. The course website is rich in content and illustrated, which provides a convenient teaching platform for students' personalized autonomous learning and teachers' multimedia teaching, and realizes resource sharing. Relying on the educational reform projects at all levels, a reasonable and hierarchical curriculum teaching system has been established, and a multi-level and diversified teaching model has been realized, which has achieved landmark results: 2 first prizes for teaching achievements at or above the provincial and ministerial levels, 3 second prizes 1, 3 third prizes, 2 first prizes for national appraisal, and many school-level teaching achievement prizes. Compiled and published 13 textbook, and established a complete three-dimensional textbook system.
In a word, the main characteristics of the development of college physics curriculum in our school are: the reform of education and teaching runs through, with an early start, a high starting point and great efforts, focusing on improving the effectiveness of students' scientific quality. Because the course of College Physics in our school is conducted under the guidance of the Steering Committee of Engineering Physics Course of the Ministry of Education, we can constantly learn new ideas, gain new experiences and make our own new contributions in the interaction with colleagues in brother colleges who actively participate in the reform.
