In the last decade, micrometer-sized lenses have been found to be able to resolve objects beyond the diffraction limit. Despite the fact that the possible nature of this phenomenon has been discussed in many works, a detailed theory of this phenomenon has not yet been developed. In this paper, two possible models of this phenomenon are discussed using the matrix formalism in imaging. The first model considers the transformation of the source field, with the real image unchanged. The second model is based on the search for the scattering matrix of a particle that gives over resolution in a virtual image. Both approaches convincingly demonstrate the required over resolution. Disadvantages of the proposed models and possible ways to solve them are discussed.
