Abstract

A new diffraction synthesis method is proposed for computing quasioptical 2-D reflector beam splitters in the E-polarization case. It is a combination of a numerical gradient (NG) optimization and an efficient analysis method based on singular integral equations (SIEs) which are discretized using a fast and accurate numerical Nystrom-type method of discrete singularities (MDS). The results of design are shown for a 40-quasioptical power splitter obtained from an offset parabolic reflector fed by in-focus beam source.
二维准光功率分路器的数值衍射合成
提出了一种新的衍射合成方法,用于计算e偏振情况下的准光学二维反射器分束器。它是数值梯度优化和基于奇异积分方程的高效分析方法的结合,奇异积分方程采用快速、精确的数值nystrom型离散奇异点方法进行离散。本文给出了一种40准光功率分配器的设计结果,该分配器由聚焦光束源馈送的偏置抛物面反射器获得。
