摘　　要：对一种用于各向异性媒质的全新时域数值方法(TLM算法)进行了研究。将Z变换引入TLM算法,用于处理各向异性媒质的电磁问题,推导递推计算公式。计算各向异性磁化等离子体层对电磁波的反射系数和透射系数。计算结果与解析解吻合较好,表明该法用于各向异性媒质时有高效性和高精度性。A novel time-domain numerical computation method for anisotropic media which was TLM method was studied in this paper. The implementation of the Z transform was introduced into TLM computation method analysis of anisotropic media. The recursive relation available for TLM computation method was derived. The reflection and transmission coefficients of electromagnetic waves through an anisotropic magnetized plasma layer in one dimension were computedl The results of TLM method and analytic solution were close, which proved the high accuracy and efficiency of this method for anisotropic media.
