矩形孔缝耦合特性实验研究

 对矩形孔缝在微波频率为2～18GHz范围内的耦合系数进行了实验研究；建立了实验方法和实验装置。实验结果表明：对于矩形孔缝，当入射电场方向垂直于孔缝长边时，在微波波长约等于2倍孔缝长度时，发生共振效应，在该频率附近一定带宽内耦合系数最大，并且在共振频率处存在着场增强效应。

Experimental studies on coupling characteristics of rectangular slot

This paper experimentally studies the coupling coefficient of microwaves into rectangular slots. The frequency range is from 2 to 18GHz. The experimental method is presented, and the experimental setup is established. The experimental results show that the resonant effect will take place if the microwave wavelength is twice about the side length of the rectangular slot, and if the direction of the incident electric field is perpendicular to the long side of the slot. There is a strong coupling band near the resonant frequency, around which the enhancement effect can take place.
