The loss mechanism of absorbing materials is divided into several types

Author:admin   AddTime:2021-06-28

Absorbing material refers to a type of material that can absorb the electromagnetic wave energy projected on its surface. Then the loss mechanism of the absorbing material is mainly as follows:

First: resistive loss

This kind of absorption mechanism is related to the resistive loss related to the conductivity of the material, that is, the greater the conductivity, the greater the macro current (including the current caused by the electric field change and the eddy current caused by the magnetic field change) caused by the carrier, which is beneficial to electromagnetic energy. Converted into heat energy.



Second, dielectric loss
Absorbing materials are a kind of dielectric loss absorption mechanism related to electrodes, that is, through the "friction" effect of 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.

Third, magnetic loss
This kind of absorption mechanism is a kind of magnetic loss related to the dynamic magnetization process of ferromagnetic medium. This kind of loss can be refined into: hysteresis loss, gyromagnetic eddy current, damping loss and magnetic aftereffect, etc. The main sources are and Magnetic domain turning, domain wall displacement, and natural resonance of magnetic domains with similar magnetic mechanisms.
