摘要
利用时域有限差分方法计算金属与等离子体复合目标的电磁散射,用移位算子法分析色散介质的时域本构关系。并对复合目标RCS与等离子体频率和碰撞频率的关系进行了计算和分析。
By using FDTD method, the electromagnetic scattering from the combinative objects with metal and plasma is obtained, and the time domain consititutive relation of dispersive medium is analyzed with the shift operator. The relationship of combinative objects＇PCS and the plasma frequency and electron collision frequency is calculated and analyzed.
