摘要:
应用(FD)2TD数值方法对电磁波作用于等离子体上的反射系数幅值和相位进行了研究,并与解析解进行了比较,证明了该方法的正确性。应用该数值方法计算了等离子体频率分别为10、20和30 GHz三种情况下的电磁波反射系数和相位,以及碰撞频率分别为5、10和20GHz三种情况下的电磁波反射系数和相位,并分析了反射系数和相位的变化规律,结果表明:等离子体频率对反射系数幅值和相位的影响较大,但总趋势基本一致;而碰撞频率对反射系数幅值和相位的影响很小,大部分情况下几乎可以忽略不计。
Abstract:
A frequency-dependent finite-difference time-domain( ( FD) 2 TD) method is applied to study theamplitude of the electromagnetic reflectioncoefficient andphase. Compared with an analyt-i cal resolution, the high accuracy of  this method is verified. The electrom agnetic reflection coefficient and phase are calculated respectively with different plas mafrequenciesof 10, 20 and 30GHzandcolli- sion frequencies of 5, 10 and 20GHz. Their regularities are also studied. The results show that  the plasm a frequency affects the amplitude of  the reflection coefficient and phase sharply, but the collision frequency shows a less and negligible effet.
