Karpusha, Registration Date 02-04-2010 Organization Sumy State University popup.description2 Aim: To gain adequate mathematical model of the solution of a inverse problem of ellipsometry. Object of research: inverse problem. Subject of research: inverse problem of ellipsometry (IPE). Method of research: spectoellipsometrical method of Beatty-Konna, optimization and statistical methods of solution of IPE. In present paper mathematical models of the decision of a inverse problem of ellipsometry have been offered. They have been based on use of optimization and statistical methods. Conditions and limits of their use have been considered. Accuracy of the offered approaches of the decision of the problem have been estimated. Optical parameters of amorphous alloys Ni85C15, Ni40Fe40B20, Ni40Fe50B10 have been obtained. Product Description popup.authors popup.nrat_date 2020-04-02 Close
