Abstract
An iterative procedure based on pseudosampling is presented for the analysis of subreflector Fresnel fields on an arbitrary surface. The method improves the efficiency of the subreflector PO analysis which, today, is the only available technique for dichroic surfaces. The procedure retains all the advantages of the pseudosampling technique with respect to the computer time, mainly for multifeed illuminations and complex geometries.
