Abstract
In a recent work [M. G. Silveirinha, C. A. Fernandes, J. R. Costa, Phys. Rev. B, 78, 195121, 2008], we have theoretically demonstrated that a micro-structured material formed by a very dense array of crossed wires can be used to enhance the near-field and achieve subwavelength imaging. Here, we describe our ongoing work in this topic, and discuss the physical principles and the salient features of the imaging mechanism.
