Paper Abstract

By evaporating an infinitely thin layer of perfectly conducting metal on the small facet of the groove of a dielectric echelette grating then by superimposing an adequate inhomogeneous layer on top of the large facet, it is shown that a theoretical efficiency of 100% is obtained in a transmitted order. A numerical proof of this theoretical prediction is achieved using a computer code based on a rigorous finite-elements method. The curves of efficiency near the blazing effect show remarkable widths.
