Abstract

Summary form only given. Recently Pao, Dvorak, and Dudley (see IEEE Antennas and Propagation, vol.44, no.7, p.918-32, July 1996) did some work to efficiently evaluate the solution of a transient plane wave incident on a lossy half-space. We can now use this solution to obtain the incident wave solution in the FDTD method. To test out this concept, we consider a two-dimensional FDTD code which utilizes the anisotropic PML as the outer boundary condition. The solution is compared to those obtained from the "brute force" approach with the inverse Fourier transform. Also, the computation time results are compared to demonstrate the efficiency of our method versus the "brute force approach".
