With the continuous development of science and technology and the continuous expansion of human activities, microelectronics and computer technologies have been applied to all aspects of social life. A large number of electrical and electronic products with high technical content and complex internal structures have been widely used, making them increasingly information and Electromagnetic sensitization. The impact of the complex electromagnetic environment on the earth and mankind has attracted more and more attention. Therefore, it is of great significance to study the mechanism of electromagnetic coupling.

The electromagnetic environment refers to the sum of all electromagnetic phenomena that exist in space. Various man-made electromagnetic radiation and natural electromagnetic radiation constitute a complex electromagnetic environment. Among them, man-made electromagnetic radiation includes mobile phones, radio dialogue machines, radio and television transmitters, satellites, radars, etc., lightning, static electricity, geomagnetic field, sunspots, etc. Activities, cosmic rays, etc. constitute natural electromagnetic radiation sources.

  The formation of electromagnetic radiation requires the following three elements at the same time:

   Electromagnetic wave source refers to the components, equipment, systems or natural phenomena that produce electromagnetic waves;

  Coupling channel refers to a channel or medium that couples or propagates energy from a wave source to a sensitive device and makes the device respond;

   Sensitive equipment refers to equipment that responds to electromagnetic waves
