摘要

在电磁仿真中，适当的波导模板激励是实现快速准确时域有限差分建模的关键因素之一。在一些特殊但实际的情况下，众所周知的单点激励模板生成方法[1]可能会导致数值问题:它可能是病态的和/或缓慢的。本文介绍了利用一组激励点激励二维波导模板来改善数值条件的方法。

Multipoint excitation in the FDTD eigenmode port template generation

Proper waveguide template excitation in EM simulations is one of the key factors to perform fast and accurate FDTD modelling. In some special, but practical cases, the well-known template generation method [1] with one point excitation can lead to numerical problems: it can be ill-conditioned and/or slow. In this paper, it is presented how to improve numerical conditions by exciting 2D waveguide template using a set of excitation points.
