Abstract

In this report we exploit numerically a novel cascaded plasmonic superlens system for far field subwavelength imaging, which is a promising solution to the current existing problem with near field superlenses. In our approach, a metamaterial composed of a double layer metallic meander cavity (DLMC) structure is used to support the propagation of waves with large transverse wave vectors. Then a planar plasmonic lens (PPL) cascaded with the DLMC is used to couple the near field waves into free space to form an image with magnification via phase compensation. We study numerically the whole coupled system in the near and far field regime to demonstrate the functionality of such a superlens and near field interaction among them is discussed.
