本文对运动和/或振动的理想导电表面反射的电磁脉冲进行了一维模拟。利用特征变量和相对论边界条件，应用特征线法得到了计算结果。反射的理想表面被设置为以相对较高的速度持续运动和/或以很高的频率正弦振动，以便容易地观察到对反射脉冲的相对论效应。为了验证数值方法的有效性，给出了反射电场和相应的频谱，并与理论多普勒位移值进行了比较。结果表明，计算结果与理论值吻合较好。
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.
