C-Method: From the Beginnings to Recent Advances

Abstract

C-method – is simple and rather clear for code implementation and it enables to resolve efficiently diverse applied problems of optics and spectroscopy. Although the method cannot be treated as completely mathematically rigorous, in the case when the principal characteristics of grating are required, the C-method provides the data of applied interest with engineering accuracy.

In this chapter the principal ideas making the background of classical C-method and its latest modifications have been described concisely. The physical results demonstrating the considerable potentialities of the method for resolving actual fundamental and applied problems of electromagnetic theory of gratings are also presented.
