Abstract

Berenger´s PML technique is modified to allow for the absorption of evanescent waves, as well as propagating waves, in FDTD modeling of wave propagation in planar waveguiding structures. Analytical results are used to illustrate the validity and capability of the proposed modification. Results from FDTD and compact 2D-FDTD simulations demonstrate its performance.<>
