Parameters Optimization Algorithm of a New Type of Diffraction Optics Elements

Abstract

A new methods of construction and optimization of diffraction optics elements with square zones topology which allow to greatly reduce a sidelobe level by rotating square zones relative to each other are presented. The method of finding maximal of sidelobe level using multiple runs of local search algorithms and zones rotation angles optimization algorithm based on principles of optimizing multiextremal table functions were used. So these elements, for example in microelectronics and THz waveband, can be produced on standard equipment used in chips manufacture.
