Mismatch of perfectly matched layers (PML) in cylindrical and spherical coordinate system

Research output: Contribution to conferencePaper

Abstract

In this paper, the generalized theory for perfectly matched layers (GT-PML) that was presented as a systematic development of the unsplit-field formulation of perfectly matched layers in Cartesian coordinates, is extended to investigate the absorbing properties of perfectly matched layers in cylindrical and spherical coordinates. Several differences are identified between PML in Cartesian coordinates and PML in cylindrical or spherical coordinates. It is concluded that no PML can be constructed in cylindrical and spherical coordinates as it has been done in Cartesian coordinates. The theory presented in this paper is also validated by FDTD simulation on the cylindrical grid.
