1.2 Electromagnetic radiation causes direct and indirect damage to the human body through thermal effects, non-thermal effects, and cumulative effects. The research confirmed that the ferrite absorbing material has the best performance. It has the characteristics of high absorption frequency band, high absorption rate, and thin matching thickness. The application of this material in electronic equipment can absorb the leaked electromagnetic radiation and can achieve the purpose of eliminating electromagnetic interference. According to the law of electromagnetic waves propagating in the medium from the low magnetic guide to the high magnetic guide direction, the high magnetic permeability ferrite is used to guide the electromagnetic waves. Through resonance, a large amount of electromagnetic wave radiation energy is absorbed, and then the electromagnetic wave energy is converted into thermal energy through coupling.

First, resistive losses, such  absorption mechanism and the resistive loss of the material's conductivity, that is, the greater the conductivity, the macroscopic current caused by carriers (including the current caused by changes in the electric field and the eddy current caused by changes in the magnetic field) The larger, which is conducive to the conversion of electromagnetic energy into heat energy.
Second, dielectric loss, it is a kind of electrode-related dielectric loss absorption mechanism, that is, the "friction" generated by repeated polarization of the medium converts electromagnetic energy into thermal energy and dissipates it. The dielectric polarization process includes: electron cloud displacement polarization, polar medium electric moment turning polarization, electric iron body domain turning polarization, and wall displacement.
