Electrical engineering (electrical engineering? EE) is one of the core disciplines in the field of modern science and technology, and it is also an indispensable key discipline in the field of high-tech electrical engineering. For example, it is the great progress of electronic technology that promotes the arrival of the information age based on computer network and will change the life and work mode of human beings. The development prospect of electrical engineering also has great potential, which makes the employment rate of students today always defined as the sum of related disciplines used to create and produce electrical and electronic systems. The field of electrical system is a field full of hopes and challenges. It is said that electrical system belongs to engineering specialty because the challenge of engineering lies in designing all circuit systems and clustering them into a whole. Cyber-physical systems is the most representative frontier circuit system, including Internet of Things, pervasive computing and sensors.

Electrical engineering [2] is one of the core disciplines in the field of modern science and technology, and it is also an indispensable key discipline in today's high-tech field. In a sense, the degree of development of electrical engineering represents the level of scientific and technological progress of the country. Because of this, the education and scientific research of electrical engineering has always occupied a very important position in universities in developed countries.

Among the institutional names of electrical engineering in American universities, some schools are called the Department of Electrical Engineering, some are called the Department of Electrical Engineering and Information Science, and some are called the Department of Electrical Engineering and Computer Science. This discipline (department) is very different from the domestic electrical engineering discipline in scientific research, teaching and academic organization. Understanding the situation of foreign disciplines and the direction of teaching and research plays a very important role in adjusting the direction of disciplines and improving the level of teaching and research.

Traditionally, electrical engineering has been defined as the sum of related disciplines used to create and produce electrical and electronic systems. This definition is very broad, but with the rapid development of science and technology, the concept of electrical engineering in 2 1 century has gone far beyond the above definition. Professor Stanford University pointed out that today's electrical engineering covers almost all engineering behaviors related to electrons and photons. The huge growth of knowledge in this field requires us to re-examine and even reconstruct the subject direction, curriculum and content of electrical engineering, so that the subject of electrical engineering can effectively respond to the needs of students, the needs of society, the progress of science and technology and the dynamic research environment.
