The phenomenon of the superresolution of flat lenses is considered based on experiments with phononic and photonic crystals with negative dispersion. An analysis of the frequency dependence of focal lengths within the ray theory made it possible to determine negative refractive indices and to obtain phase mismatches of axial and off-axial rays forming the focal spot not exceeding 1/40 of the radiation wavelength. The observed phenomenon is interpreted in terms of the quantum theory.
