Analysis of UPML Design Parameters in the Solution of Electromagnetic Scattering Problems

摘要

In this work, the UPML design parameters are analyzed for solving electromagnetic scattering problems using the Finite Element Method (FEM). Analysis are presented for the maximum conductivity and thickness of the absorbent layer. The results show that small values of the conductivity may not adequately represent the decay of the fields while high values may generate reflections. The thickness of the layer, in turn, must have a minimum value to guarantee the convergence of the solution.
