Analysis of Electromagnetic Scattering by the Finite-Difference Complex Frequency Domain Method - Combination with FILT for Studying Time-Domain Responses

摘要

In recent years, many computational methods for electromagnetics have been proposed. The FDFD (Finite-difference Frequency-Domain) method is a numerical solver of Maxwell's equations in frequency domain using the finite-difference scheme. In this paper, we develop the formulation of the FDFD method in complex frequency domain and perform time domain analysis of electromagnetic scattering by a metallic cylinder using combination with FILT (Fast Inverse Laplace Transform).
