Abstract

In a recent paper [ Appl. Opt. 34, 2556 ( 1995)] beam-splitter gratings with one or more v-shaped features within the period were designed by the complex-amplitude transmittance method. We argue that this approach leads to incorrect results in the geometries considered and provide the evidence of its failure by numerical calculations based on rigorous electromagnetic diffraction theory.
