An inverse filter full analytical description and implementation of a recently proposed plasmon injection scheme for improving the resolution of a hyperlens is presented. Different types of loss mechanisms existing in the hyperlens imaging system are identified and studied in detail. It is shown that the plasmon injection scheme and its inverse filter analog can compensate all the major loss mechanisms. As a result, an object with deep subwavelength features, otherwise unresolvable with a hyperlens alone, is fully reconstructed
