Rigorous formulation for electromagnetic planewave scattering from a generalüshaped groove in a perfectly conducting plane: Comment

Abstract

We show that the problem of scattering of an obliquely incident plane wave by a generalüshaped groove engraved on a perfectly conducting plane, which was recently studied by Basha et al. [J. Opt. Soc. Am. A 24, 1647 (2007)], was solved 11 years ago using the same formulation. This method was further extended to deal with a finite number of grooves and also with complex apertures including several nonlossy and lossy dielectrics, as well as real metals. © 2008 Optical Society of America.
