摘要

本文把保角变换应用于紧凑格式2D/FDTD算法

给出了保角变换FDTD算法差分公式

提出了焦点的处理方法.用Cassinian变换分别计算了椭圆波导、茧形波导的截止波长与色散曲线

以及屏蔽平行双线高阶模的截止波长.

Abstract

In this paper

we apply conformal mapping into compact 2D/FDTD algorithm

gave the difference formula of conformal mapping FDTD algorithm

propose the treatment method of focus.The cutoff wavelengths and dispersion curves of elliptic and of cocoon-section waveguides are calculated

and the cutoff wavelengths of high order modes of shield two parallel lines are also given by this method.
