2. Dielectric loss. It is a kind of dielectric loss absorption mechanism related to the electrode, that is, through the "friction" effect generated by repeated polarization of the medium, the electromagnetic energy is converted into heat and energy consumption is dissipated. The dielectric polarization process includes: electron cloud displacement polarization, polar dielectric moment turning polarization, electric ferrite domain turning polarization, and wall displacement.
With the development of modern science and technology, the impact of electromagnetic radiation on the environment is increasing. At the airport, the flight cannot take off due to electromagnetic wave interference, and the time is delayed; at the hospital, mobile phones often interfere with the normal operation of various electronic medical equipment. Therefore, the treatment of electromagnetic pollution and the search for a material that can withstand and weaken electromagnetic wave radiation-absorbing materials have become a major issue in materials science.
