Abstract

The Perfectly Matched Layer (PML) has recently been introduced by Berenger as a material absorbing boundary condition for electromagnetic waves and applied in two- and three-dimensional FDTD simulations. In this paper, the parameters defining a multilayer discrete PML medium terminated by a conducting plane are optimized to minimize the absorber's reflection coefficient over a specified range of frequencies and incident angles. This optimization is performed using a Genetic Algorithm and results in profiles quite different from the commonly used linear and quadratic ones.
