Diffraction gratings of isotropic negative-phase velocity materials
(Elsevier Gmbh, 2005-12)
Diffraction of electromagnetic plane waves by the gratings made by periodically corrugating the exposed planar boundaries of homogeneous, isotropic, linear dielectric-magnetic half-spaces is examined. The phase velocity ...
On metallic gratings coated conformally with isotropic negative-phase-velocity materials
(Elsevier Science, 2008-12)
Application of the differential method (also called the C method) to plane-wave diffraction by a perfectly conducting, sinusoidally corrugated metallic grating coated with a linear, homogeneous, isotropic, lossless ...
Enhanced diffraction by a rectangular grating made of a negative phase-velocity (or negative index) material
(Elsevier Science, 2005-12)
The diffraction of electromagnetic plane waves by a rectangular grating formed by discrete steps in the interface of a homogeneous, isotropic, linear, negative phase-velocity (negative index) material with free space is ...
Experimental and theoretical analysis of the intensity of beams diffracted by three-dimensional photonic crystals
(American Physical Society, 2008-12)
An analysis of the diffracted beams emerging from three-dimensional photonic crystals is herein presented. The wave vectors of nonspecular beams are calculated for a triangular two-dimensional lattice and the change in ...
