利用坐标系转换矩阵给出实验室系中饱和磁化铁氧体的频域磁化率张量,采用部分分式展开方法通过Z变换得到磁化率张量的Z域形式,给出了任意磁化方向铁氧体电磁散射的Z变换-时域有限差分算法.计算了饱和磁化铁氧体球的同极化和交叉极化后向雷达散射截面,结果表明了算法的正确有效性.
The frequency-domain susceptibility tensor of the saturated magnetized ferrite in the laboratory system is given by using the coordinate transformation matrix. The Z-domain form of the susceptibility tensor is obtained by the Z-fractional partial expansion method. The magnetization direction of any magnetized iron Z-Transform-Time-Domain Finite Difference Algorithm for Electromagnetic Scattering of Oxygen The calculated cross-sections of radar cross-sections after co-polarization and cross-polarization of saturated magnetized ferrite balls have been calculated. The results show the correctness of the algorithm.
