摘要

提出了一种将复杂孔径模型纳入时域有限差分法的新方法。而不是解决几何细节的孔径，孔径被视为一个磁偶极子。磁偶极矩的性质是通过测量孔径的透射截面来确定的。这种半经验模型允许在时域有限差分模拟中包含复杂的孔径。仿真结果与实测结果进行了比较。

Semi-empirical modeling of apertures by use of FDTD

A novel method to include models of complex apertures into the finite-difference time-domain method is presented. Instead of resolving the geometrical details of the aperture, the aperture is treated as a magnetic dipole. The properties of the magnetic dipole moment are determined using the measured transmission cross section of the aperture. This semi-empirical model permits inclusion of complex apertures in FDTD simulations. Comparisons between simulations and measurements are presented.
