Propagation of Electromagnetic Pulse Onto a Moving Lossless Dielectric Half-Space: One-Dimensional Simulation Using Characteristic-Based Method

Abstract

This paper provides one-dimensional numerical simulation results of the propagation of plane electromagnetic (EM) pulse onto a dielectric half-space that is constantly moving. The governing equations are numerically solved using characteristic-based method. The medium employed in the one-dimensional model is assumed to be homogeneous, isotropic, lossless, and linear, and moving with a constant velocity of one tenth of the light speed. The velocities of EM pulses inside moving media are investigated by comparing with the analytical values predicted by the theory of relativity. The effects of the moving dielectrics on the reflected and transmitted electric fields are examined by comparing them side-by-side. Also shown are the corresponding spectra.
