Computational design for multi-layer absorber

The calculation and design theory for multi-layer absorber is present. Specially, the results of calculation and design for single, double and multiple layers absorber are given. The energy attenuation and frequency bands of absorber toward the incident wave are predicted. In order to prove the design result mentioned above, a serial of experiments were operated by means of surface-coating techniques. Technique index, such as frequency bands, absorption peak location and energy attenuation, were also measured. The results of calculation are consistent with experiments or the whole.
