摘要

本文导出了双层复介电常数圆柱体散射场的矩阵解公式

并用所模拟的散射场定量研究了用滤波-反投影技术计算出的介质柱内部介电常数分布特性。文中给出了介质圆柱的二维径向分布曲线以及由重构图象矩阵中统计回收计算出的介电常数损耗。

Abstract

Scattering fields from dielectric cylinders with a structure of two layers are simulated using numerical matrix methods. The fields obtained are used to calculate the internal characteristics of cylinders by means of Filter-Back projection techniques. The radial distribution of phase and the amplitude of complex permittivity for cylinders are given with the loss tangent values retrieved statistically from the reconstructed image matrix.
