Abstract

In this report one-dimensional simulation of Electromag- netic pulses reflected from moving and/or vibrating perfectly conduct- ing surfaces is presented. The computational results are obtained through the application of the method of characteristics with the aid of the characteristic variable and the relativistic boundary conditions. The reflecting perfect surface is set to constantly travel at relatively high speed and/or sinusoidally vibrate with very high frequency in or- der to easily observe the relativistic effects on the reflected pulses. To validate the numerical method, the reflected electric fields and the cor- responding spectra are demonstrated side-by-side for comparisons with the theoretical Doppler shift values. It is found that the computational results and the theoretical values are in good agreement.
