【Abstract】 Applying the Geometrical Optical Principle and Tracing Method, analysis and dis cussion on the absorbing material used in microwave anechoic chambers are given. It shows that the performance of this kind of material depends on the multi-re flection on the pyramidal interface and the inner attenuation. All of these beha viors depend on the complex permittivity of the material. By means of CAA and CA D, association is established between absorbing performance and configuration al ong with parameters of the material.更多还原
