Abstract

At the interface of two materials with different permittivity and permeability, evanescent waves are excited and will constrain perfect imaging using: left-handed meta-materials (LHMs). Piecewise-linear recursive convolution dispersive finite-difference time-domain method is used to demonstrate that stacks, which consist of thin alternating layers of conventional materials and LHMs, can guide evanescent waves with some attenuation at microwave frequencies and over large stack thicknesses.
