Abstract

This paper presents derivation of anisotropic quasi-perfectly matched layers absorbing boundary condition in generalized orthogonal coordinates (GOC).The anisotropic quasi-perfectly matched layers absorbing media in rectangular coordinates

cylindrical coordinates and conformal mapping cylinder coordinates are given in this paper.Numerical results illustrate the effectiveness of absorbing in anisotropic perfectly matched layers.
