Paper Abstract

Coating lenses are membranes made of materials exhibiting negative index of refraction and deposited on other media with high dielectric constant ε3. Unfortunately far-field imaging suffers from centrosymmetric aberrations. We propose a simple procedure to compensate partially deviations from ray-tracing perfect imaging in asymmetric metamaterial lenses. We also show that, under some circumstances, coating superlens may recover subwavelength information transmitted in a relative spatial spectrum ranging from 1 to √ε3.
