Subwavelength Target Detection Using Ultrawideband Time-Reversal Techniques With a Multilayered Dielectric Slab

Abstract

We employed a multilayered dielectric slab to implement subwavelength target detection by utilizing ultrawideband (UWB) time-reversal (TR) techniques. Simulation results with/without the multilayered dielectric slab are presented to show the benefit of the multilayered dielectric slab structure using finite-difference time-domain (FDTD) method.
