Abstract

A detailed study of evanescent waves in a two-dimensional photonic crystal known to be a left-handed medium for propagating modes is presented. We have not found universal amplification of the evanescent modes, connected with negative μ and ϵ of the bulk photonic crystal. An analytical expression for the intensity distribution near the far-field focus is obtained using diffraction theory. This distribution contains some novel features and establishes a new diffraction limit for flat lenses. The distribution is generalized for multiple sources located at different points and is in very good agreement with computer simulations.
