Scattering of light from metamaterial gratings with finite length

Abstract

Using an integral equation approach based on the Rayleigh hypothesis, we investigate the scattering of a plane wave at the rough surface of a metamaterial with a finite number of sinusoidal grooves. To show the adequacy of the model, we present results that are in agreement with the predictions of physical optics and that quantitatively reproduce the polarization and angular dependences predicted by the Cformalism for metamaterial gratings with an infinite number of grooves. © 2012 Optical Society of America.
