The classification of absorbing material loss mechanism?

As everybody knows, the absorbing material refers to the can absorb electromagnetic energy projected on the surface of a material. Absorbing material loss mechanism can be divided into several categories, then will solve for you.

1. The type of resistance loss, associated with the electrical conductivity of the material. That is to say, the greater the conductivity, caused by the carrier the macro current (including current caused by the electric field change and caused by the eddy current magnetic field changes), the greater the that makes the electromagnetic energy is converted into heat energy.

2. The dielectric loss is related to the electrode of a dielectric loss absorption mechanism, electromagnetic energy is caused by dielectric polarization repeatedly "friction" effect is converted into heat energy consumption and dissipate. Dielectric polarization process include: electron cloud displacement polarization and polarity dielectric torque polarization, polarization and ferroelectric domain wall displacement.

3. Magnetic loss. The absorbing mechanism is a related to the dynamic magnetizing process of ferromagnetic medium magnetic loss. This loss can be subdivided into: hysteresis losses, eddy current, damping loss and magnetic after effect and so on. Its main source is the direction of the magnetic domain and magnetic domain wall displacement and magnetic domain inherent resonance, similar to the mechanism of hysteresis. In addition, the microwave loss mechanism of nanometer materials is a hot spot in absorbing material analysis.
