Calculation and Experimental Verification of Normalized Electric Field in Reverberation Chamber’s FDTD Simulation
摘要/Abstract
采用时域有限差分（FDTD）法对尺寸为10.5m×0.8m×4.3m的混响室进行了三维仿真计算，为实现仿真与实测结果关于归一化电场强度的直接对比，给出了仿真电场值的归一化计算方法，并做出实验验证.结果表明：所提出的处理方法是合理可靠的，归一化电场强度与激励源无关，是表征混响室自身谐振特性的参量，因此可用频域测试结果对时域仿真结果进行实验验证，这为基于时域宽频仿真的混响室优化设计提供了有益参考.
A reverberation chamber(RC) with the size of 10.5m×0.8m×4.3m is simulated by the finite difference time domain(FDTD) method.In order to realize the direct comparison between simulated and measured normalized electric field strength, a reliable method is proposed for the normalization of simulated electric field with measurement verification.Through simulation and measurement, the normalized electric field strength is found to be a parameter embodying the RC's intrinsic resonant characteristics, which are independent of the driving source.Therefore, it is feasible to validate the time-domain simulation results by frequency-domain measurement.The optimum design of a RC based on time-domain simulation can draw a certain referential value from this conclusion.
