Comments on electromagnetic scattering from inhomogeneous impedance periodic rough surfaces by transform technique

Abstract

AbstractIn an recent article by Tezel (Microwave and Optical Technology Letters 51 (2009), 116–119) an electromagnetic scattering problem related to a periodic rough surface having an inhomogeneous standard impedance boundary condition is considered. The author proposes a solution method, which is based on the equivalent representation of the rough surface in terms of a planar one with higher order impedance boundary condition. We have already noticed that the mathematical formulation of the problem is completely incorrect and such a rough surface cannot be equivalently represented in terms of higher order impedance boundary condition. Therefore, the numerical results has no reliability, and they are fictitious. © 2009 Wiley Periodicals, Inc.
