Paper Abstract

We identify the conditions of imaging using a metal-dielectric nanolayered superlens within the regime of resonant tunneling that allows for superresolution. Resonant tunneling is a mechanism which leads to effective transparency of metals present in nanolayered stacks. The resonant tunneling operation regime is based on the coupling of incident waves to Bloch waves through the external layers which minimize reflection. This regime enables transmission within a broad spectral range through layered metallic structures with the total thickness reaching several wavelengths. We consider imaging from the near field to the near field and aim at increasing of the lens-image distance. We show that under certain conditions imaging with subwavelength resolution is possible. The present analysis relies on full-wave modeling based the transfer matrix method (TMM) and the finite-difference time-domain (FDTD) method.
