摘要
本文研究二维非均匀有耗介质柱在电极化二维脉冲波激励下的瞬态散射。采用分片双线性插值的空间离散方案,经解析处理,子域上的积分能得到闭式结果。离散化方程在复频域用CG-FFT法求解,并用一种新外推法产生初值,数值结果证实了本文方法的有效性。
The transient scattering of an electrically polarized,2-D pulsed wave by 2-D inhomoge-neous,lossy dielectric cylinder is investigated.In space discretization,a piecewise bilinear interpolation is used.THe integrals over patches are carried out analytically in closed form.The discretized equation in complex-frequency domain is sloved by using the CG-FFT method and the initial estimates are generated by using a new extrapolation scheme.Numerical results verify the efficiency of the new approach in this paper.
