Summary:
The one-dimensional simulation results of the reflection of electromagnetic waves from vibrating perfectly electric conducting planes are presented in this paper. The perfect conducting plane is set to vibrate sinusoidally or in zigzag with an impractically high frequency so that the instantaneous velocity at the equilibrium position is equal to either 10 or 20 percent of the speed of light. The reason of so doing is for the purpose of easy observation of the Doppler effects on the reflected waves. The computational results are obtained using the method of characteristics through the application of both characteristic variable and relativistic boundary conditions. By comparing the computational results with the theoretical Doppler shift values, the accuracy of the numerical method is investigated. It is found that the predicted data are in good agreement with the exact values.
