Full text of article: Russian language.

Abstract:
A modeling of the focusing of linear-polarized light by a binar cylindrical lens, analog of gradient Mikaelian lens was carried out for a visible light with a wavelength of λ = 0.532 nm. The refraction number of the lens is n = 1.56, which corresponds to electronic resist. The minimum focus spot diameter at the end side of the lens was calculated full width half maximum as 0.37 of the wavelength . Efficiency of the focusing is equal to 41%. Modeling was carried out in by FDTD-method in the commercial program FullWave, Rsof design group.

Key words:
gradient binar lens, photonic crystall, planar waveguide, cylindrical lens.
