摘要

本文研究了超宽带(UWB)电磁脉冲穿过狭缝进入矩形空腔的耦合效应问题。采用时域有限差分(FDTD)方法分析了不同槽面坡度对腔内耦合的影响。结果表明，当所有槽的面积相同时，垂直于入射波电场极化方向的宽边矩形槽的能量穿透量最大。

Numerical solution on coupling of UWB pulse into a rectangular cavity through slots

In this paper, the problem of coupling effects of ultra-wide-band (UWB) electromagnetic pulse into a rectangular cavity through slots is investigated. The finite-difference time-domain (FDTD) method is used in analyzing the effectiveness of various slot slopes on coupling into the cavity. It is demonstrated that the energy penetration of rectangular slot with wider side, perpendicular to the incident wave's electric field polarized direction is maximum on condition that all slots presented have same area.
