Abstract:In this dissertation the idea of a higher-order perfectly matched layer (PML) is proposed. Using a metric coefficient that includes both the regular and the complex frequency shifted (CFS) PMLs, it is possible to obtain a PML that includes the advantages of both of them. The second-order PML is applied to waveguide, periodic, and open-region electromagnetic problems and its performance is compared to the regular's and the CFS-PML's performance. The second-order PML outperforms both and its performance is proved to be independent of the formulation or the simulation technique, since the same behavior was observed using a stretched-coordinate approach in finite-difference timedomain and uniaxial PML in time-domain finite-element method.
