摘要

本文研究了电磁波与内含导线的矩形腔之间的小孔耦合。利用Bethe小孔理论和细线近似简化了计算。具体求解和计算了谐振频率

以及谐振状况下的小孔等效磁流、导线电流和腔内电场分布。

Abstract

The electromagnetic coupling between an incident plane wave and a conducting cavity with a conducting wire in it through a small hole is studied. Bethe’s small-hole theory and thin wire approximation are applied to simplify numerical calculations. Resonant frequencies

equivalent dipoles over the hole

induced currents on the wire

and electrical fields in the cavity at resonances are derived and calculated in numerical examples.
