摘要
本文讨论了微波脉冲与孔缝耦合在电磁兼容研究中的重要性,并用实验方法和数值模拟方法研究了微波脉冲与腔体上孔缝的线性耦合过程,给出了部分数值模拟结果和初步的实验结果.分析了耦合对入射波载频、入射场偏振方向和孔缝尺寸的依赖关系,得出了微波脉冲与孔缝耦合的共振效应和增强效应等规律,同时也给出了共振发生的条件.
In this paper, we discuss the importance of investigations on microwave pulse couplings with slots for the studies of the electromagnetic compatibility, and study the coupling processes of microwave pulses into slots on a cavity wall experimentally and numerically. Some numerical simulation results and preliminary experimental results are given. The dependence of couplings on the carrier frequencies and the polarization directions of the incident waves, and the slot sizes are analysed. We observe the resonant effect and enhancement effect which occur in the processes of microwave pulse couplings with slots. We also give the condition at which resonant effect takes place.
