V-groove gratings on silicon for infrared beam splitting: comment
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.

Among the sp, sp2, and sp3 hybridized orbitals, sp orbitals have the maximum s character (50%). Consequently, the electrons are held more closely to the nucleus, resulting in stronger and shorter C–H bonds that stretch at a...
