Abstract:
The paper presents the results of numerical simulation of binary diffractive lenses operation within the framework of a rigorous electromagnetic theory. It investigates the efficiency of binary lenses for the cases when the aperture radius is only a few wavelengths, and the focal length is comparable to the radius. The results of the rigorous electromagnetic theory and the scalar Kirchhoff approximation are compared. The limits of the scalar theory applicability in the calculation of binary lenses are estimated.

Keywords:
binary diffractive lenses, aperture radius, electromagnetic theory, scalar Kirchhoff approximation
