Title

Three-dimensional Numerical Simulation of Microwave Imaging Based on an Iterative Forward Reconstruction Method

Abstract

Microwave imaging can be applied in many different areas, including industrial, scientific and medical. There has been considerable interest in microwave imaging for more than two decades to complement other imaging modalities. This interest follows from the sensitivity of microwaves to the electrical properties of materials. This paper presents the numerical simulation of microwave reconstruction of dielectric and conductive property distribution of an object based on scattered field measurements at several locations, when the object is illuminated by an incident plane electric field. Starting from an integral equation, and using the method of moments, a spatial forward iterative algorithm is used for stability and convergence. Using this technique, both two-dimensional and three-dimensional objects are reconstructed.
