摘要
本文从磁化等离子体中电子的广义运动方程出发,给出了一套FDTD计算公式,克服了卷积递归法不适用于直流入射以及小信号近似的缺点,其正确性由数值计算结果得到验证。
In this paper,a set of FDTD fomulation of magnetized plasma is derived,which involves electron motion equation of magnetized plasma under electromagnetic field. This has overcome the defects of rescursive convolution method which is not suitable for the incident pulse with D. C component and is small signal approximation. The accuracy of this method is demenstmted by numerical computations.
