摘要：

This paper presents a method for introducing a soft source in the pseudospectral time-domain algorithm. In this method, a scalar weighting term zeta is introduced in the total field/scattered field approach in computational electromagnetics. Using our modified version of Maxwell's equations, soft sources can be introduced simply by adding incident terms in the 8-10-cell connecting region between the total field and the scattered field. One-dimensional (1-D) and two-dimensional (2-D) examples of soft source generation and a 2-D scattering study of a dielectric cylinder are given.
