Abstract

A new reconstruction algorithm as applied to electromagnetic imaging is proposed. It is aimed at reconstructing constitutive parameter distributions of infinitely long dielectric cylinders with arbitrary cross section, from the scattered fields they produce. Computer simulations show that the implementation of the pseudoinverse transformation in this algorithm yields excellent results for thin cylinders irradiated by transverse magnetic (TM) waves, even in the presence of realistic uncertainties in the scattered field measurements.

摘要

提出了一种新的重建算法，应用于电磁成像。它旨在根据它们产生的散射场来重建具有任意横截面的无限长介电圆柱的本构参数分布。计算机模拟表明，在这个算法中，伪逆变换的实现对于横向磁场 (TM) 波照射的薄圆柱产生了极好的结果，即使在散射场测量中存在实际的不确定性。
