Improved method for computing of light-matter interaction in multilayer corrugated structures: comment.
The method recently proposed by Korovin [J. Opt. Soc. Am. A25, 394 (2008)] for modeling multilayer diffraction gratings is in fact the well-known Rayleigh-Fourier method. Many remarks in the above reference in comparing the proposed method and the C method are biased and inaccurate.
