Introduction

keywords： Electromagnetic fields Electromagnetic waves University of Electronic Science and Technology of China Wang Yuan

Electromagnetic waves are a form of motion of electromagnetic fields. Electricity and magnetism can be said to be two sides of the same coin. A changing electric field will produce a magnetic field, and a changing magnetic field will produce an electric field. The changing electric field and the changing magnetic field constitute an inseparable unified field, which is the electromagnetic field. The propagation of the changing electromagnetic field in space forms electromagnetic waves. The changes in electromagnetism are like the gentle breeze blowing on the water surface to generate water waves, so it is called Electromagnetic waves are also often called radio waves.
