Implementation and application of resistive sheet boundary condition in the finite-difference time-domain method
Abstract
The implementation of the finite-difference time-domain (FDTD) method using the resistive sheet boundary condition for the analysis of E-polarized scattering from a thin resistive sheet is described. The FDTD method is validated by comparing the E-polarized scattering data for various resistive strips with the data of Senior (1979). New results on the E-polarized scattering behavior of a resistively coated dielectric strip are presented. An extension to the H-polarized case and application of the method to pulsed problems are discussed.
