Scattering of electromagnetic waves from linearly moving perfect surface using relativistic boundary conditions

The objective of this study is to demonstrate the one-dimensional numerical simulation results of the electromagnetic waves scattered from constantly moving perfect electric conductors using characteristic-based algorithm. In the model, the perfect surfaces are moving at a constant speed, either advancing toward or receding from the incident waves, The computed scattered electric field intensities are illustrated as functions of time. The predicted double-Doppler shifts are found to be in fairly good agreement with the theoretical values.
