摘要
半消声室用于30mhz ~ 1000mhz范围内的电磁兼容测量。在射线追踪分析的基础上，讨论了半消声室衬里吸收器反射率的判据。吸收体的-15 dB和-20 dB的正入射反射率足以分别满足3米和10米测量方法的标准。对于3m方法，室的尺寸可以减小到L=8 m, W=6 m和H=5 m，对于10m方法，室的尺寸可以减小到L=18 m, W=13 m和H=7 m。
Criteria for absorber's reflectivity lined in semi-anechoic chambers using ray-tracing technique
Semi-anechoic chambers are used for EMC measurement from 30 MHz to 1000 MHz. Criteria for absorber's reflectivity lined in semi-anechoic chambers are discussed based on a ray-tracing analysis. The absorber's reflectivity of -15 dB and -20 dB for normal incidence is sufficient to satisfy a standard in 3 m and 10 m measurement methods, respectively. The dimensions of the chamber can be reduced to L=8 m, W=6 m and H=5 m for the 3 m method and to L=18 m, W=13 m and H=7 m for the 10 m method.
