Abstract

Abstract

In this paper, the reflected wave of a lossy half space is computed by using the combination of Fourier transform and Fresnel formula, and it is introduced to finite difference time domain method (FDTD) calculation region by Equivalence Principle. The results by different incident planes and polarization modes are discussed. The numerical results show that the reflected wave would lead a second time energy burst when the target is located near ground. This method can be applied to computation of near field and coupling energy inside of the target. The effect of half space is not considered in existing study, this method has a basic significance of half space effect analysis for the electronic systems under HPM environment.
