Abstract
An iterative method for designing a field eikonal that creates conditions for light beam focusing to a given 2D region is considered. The eikonal function that ensures focusing from a circular to rectangular region is calculated. Application of the method to design of refractive optical elements is considered. The refractive element that focuses a plane beam with a circular section to a rectangle is designed.
