Abstract

This paper presents a feasibility study of imaging discontinuities in dielectric materials using principles of time reversal with microwaves. The principle is demonstrated by modeling the propagation of forward and time reversed electromagnetic waves using 3D finite difference time domain techniques. Simulations results validating this approach will be presented. Initial results clearly demonstrate the capability of this approach to image locations of discontinuities in materials.
