摘要：

The diffraction of a Gaussian beam with circular polarization on a gradient microlens with layers of subwave thickness was considered in this paper. Numerically, using the method of finite differences in the time domain (FDTD), I estimated the parameters of the focal lengths by the depth of the focus and the transverse dimension.
