Veselago-Pendry superlens imaging modeled with a spectral waveguide approach

A compact spectral waveguide model of a superlens imaging system based on the Fourier decomposition of the source field into waveguide modes is presented. This model maps the electromagnetics of the superlens into that of the well-understood waveguide with concomitant advantages in the analysis of dynamics and reality effects and in accurate numerical simulation. Insights into the dynamic response of the superlens, gained from both theoretical and numerical studies, are presented. The effect of loss on the dynamic properties is investigated. In addition, the proposed model leverages a wealth of expertise available for the design of filters, artificial dielectrics and backward wave structures and could possibly aid in the engineering of practical super-resolution imaging systems that will be an enabling technology for future nanoelectronics systems.
