摘要

本文给出了半消声室的建模方法。混合吸收器被表面阻抗片取代。利用测量到的反射率数据，可以确定终端片的表面阻抗。在双锥天线范围内对1m长的导线进行了测量，验证了该方法的有效性。此外，还对单极天线的腔室模型进行了验证。

Modeling of semi-anechoic chamber for use in automotive EMC simulations

In this paper, a procedure for modeling the semi-anechoic chambers is given. The hybrid absorbers are replaced with surface impedance sheets. Using the measured reflectivity data, one can determine the surface impedance of the terminating sheet. The proposed method is validated using measurements for a 1m long wire in the Biconical antenna range. In addition, chamber model is also validated for monopole antenna.
