用于电磁兼容测量的多模搅拌腔

A Mode Stirred Chamber for EMC Measurement

本文介绍新近发展的用于电磁兼容测量的多模搅拌器,并利用相应的并矢格林函数从理论上讨论了腔体内电磁场分布与搅拌器、腔体尺寸等参量的关系。只要选择合适的搅拌器进行搅拌,在腔体内产生—平均均匀的电磁场区域用于电磁兼容测量是完全可能的。

Abstract A newly developed mode stirred chamber for EMC measurement is introduced in this paper. Using corresponding dyadic Green's function,the relation between the theoretical distribution of electromagnetic field in the chamber and the parameters of tuner size and chamber size is discussed. When the proper tuner for stirring is chosen,the realization of an averagely uniform distribution of electromagnetic field in the chamber for EMC measurement is entirely possible.
