Vector theory of diffraction by gratings made of a uniaxial dielectric-magnetic material exhibiting negative refraction
(Optical Society of America, 2006-12)
Diffraction of linearly polarized plane electromagnetic waves at the periodically corrugated boundary of vacuum and a linear, homogeneous, nondissipative, uniaxial dielectric-magnetic material is formulated as a boundary-value ...
Dispersive characteristics of surface plasmon polaritons on negative refractive index gratings
(Elsevier Science, 2011-10)
The dispersive characteristics of surface plasmon polaritons (SPPs) supported by a periodically corrugated boundary between vacuum and a negative refractive index, isotropic material were studied theoretically by numerical ...
Influence of the sign of the refractive index in the reflectivity of a metamaterial surface with localized roughness
(Springer, 2011-06)
To study the scattering properties of metamaterials, we generalize two scattering methods developed for conventional (non-magnetic) isotropic materials to the case of materials with arbitrary values (positive or negative) ...
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 ...
Application of the differential method to uniaxial gratings with an infinite number of refraction channels: Scalar case
(Elsevier Science, 2006-02)
The differential method (also called the C method) is applied to the diffraction of linearly polarized plane waves at a periodically corrugated boundary between vacuum and a linear, homogeneous, uniaxial, dielectric-magnetic ...

Radiation characteristics of electromagnetic eigenmodes at the corrugated interface of a left-handed material
(American Physical Society, 2009-08)
We study the radiation characteristics of electromagnetic surface waves at a periodically corrugated interface between a conventional and a negatively refracting (or left-handed) material. In this case, and contrary to the ...
Refractive index changes in photochromic SbPO4-WO3 glass by exposure to band-gap radiation
(Elsevier B.V., 2010-10-01)
We report photoinduced photo-darkening in SbPO4-WO3 glass by exposure to 532 nm light with a power density of 143 mW/cm(2). The time of exposure was varied between 0 and 256 min following which visible photo-darkening, ...
