Abstract:
The paper considers a gradient method for the design of a multilayer dielectric cylinder with a circular cross-section, focusing a plane TE-polarized electromagnetic wave into the points with a given intensity distribution at a certain distance from the cylinder. The solution of the inverse problem of synthesis is based on the previously developed method for solving the direct problem of diffraction field calculation. In each homogeneous layer of the cylinder and outside it, the light field amplitude is expanded in rows by cylindrical functions. The unknown coefficients of these functions are calculated using recurrence relations from the equations obtained when the boundary conditions are satisfied at the boundaries of the homogeneous cylinder layers.

Keywords:
dielectric cylinder, gradient method, TE-polarized electromagnetic wave, homogeneous cylinder.
