摘要
通过对辅助方程的差分迭代 ,给出了一种新的各向异性磁化等离子体的辅助方程时域有限差分 (FDTD)算法 .并与电流密度卷积 (JEC)算法进行了比较 .通过计算磁化等离子体平板对平行于磁场传播的电磁波的反射和透射系数 ,验证了该算法的精度与JEC算法基本相同 ,而计算效率提高数倍 .
An auxiliary differential equation finite-difference time-domain (ADE-FDTD) methodology for anisotropic magnetized plasmas is derived. The method is based on a difference approximation of the auxiliary differential equation. A comparison with the JEC method is included. The CPU time saving by several times and accuracy of the method are confirmed by computing the reflection and transmission through a magnetized plasma layer, with the direction of propagation parallel to the direction of the biasing field.
