Simulation of the Field Uniformity of Anechoic Chamber

The absorber materials used in anechoic and semi-anechoic chambers and the field uniformity are described in this paper. The field uniformity of anechoic chamber is simulated with software HFSS 10.0, Ansoft. A low frequency model for absorber-arrays is obtained using the method of homogenization. The simulation result testifies the method is feasible.
