Effects of Medium Conductivity on Electromagnetic Pulse Propagation onto Dielectric Half Space: One-dimensional Simulation using Characteristic-based Method

Abstract

One-dimensional simulation results of the effects of medium conductivity on the reflection and transmission of electromagnetic pulse propagating onto a dielectric half space are presented in this paper. The computational results were produced using the characteristic-based method and compared in a side-by-side approach. In the numerical model, the material of interest is homogeneous and isotropic so that the dielectric constant, relative permeability, and conductivity are constant values and not dependent on the electric and magnetic fields. To demonstrate the effects of medium conductivity on the reflected and transmitted electromagnetic pulses, we record and illustrate these fields as functions of the time. Also shown are their corresponding spectra that are obtained through the application of proper Fourier transform.
