Quasi-Perfectly Matched Layer Absorbing Boundary Conditions for FDTD Algorithm in Generalized Orthogonal Coordinates

本文推导出了广义正交坐标系下的各向异性准完全匹配吸收层 (QPML)边界条件 ,给出了直角坐标、圆柱坐标、保角变换柱形坐标的各向异性准完全匹配吸收媒质 .

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.
