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。
Based on the generalized equations of motion of electrons in magnetized plasma, a set of FDTD calculation formulas are given, which overcomes the shortcomings of convolutional recursive method which is not suitable for direct current incidence and small signal approximation. The correctness of the method is verified by numerical calculation.
