Abstract

The realization of double negative (DNG) meta-materials and the evanescent field amplification feature of these materials engendered new approaches to subwavelength imaging. In this paper, we study the possibility of subsurface detection using evanescent fields in the presence of a DNG lens. Evanescent fields at lower frequencies can have better penetration characteristics compared to the propagating fields at higher frequencies. Using DNG materials, subwavelength images of targets buried in a homogeneous lossy medium are presented.
