摘要：

The paper considers the action of radial-layered lenses with a linear dependence of refractive index. The effect of such lenses depending on their thickness investigated. Numerical simulation based on the finite-difference time-domain method showed the possibility of sub-wavelength focusing singular Gaussian beams through such lenses.
