The electromagnetic environment refers to the types of transmission media, including transmission lines, cables, and spatial transmission media. Electromagnetic fields or electrical signals include various types of electrical signals and electromagnetic waves. The frequency ranges from close to DC and low-frequency to microwave, millimeter wave, and submillimeter wave; There are various forms of signals, including pulse type and connected wave. Some are also modulated by various modulation methods. These electromagnetic waves and electrical signals are generated by thousands or even millions of signal sources. There are many types of radiation sources, and they are complex and variable. The signal density can exceed one million pulses per second. These electromagnetic signals can directly affect the human body, producing so-called electromagnetic wave biological effects. It can also have an impact on the operation of various electrical and electronic devices, reducing their performance and even disrupting their normal operation
