Effect of in-material losses on terahertz absorption, transmission, and reflection in photonic crystals made of polar dielectrics
(A I P Publishing LLC, 2015)The effect of the material absorption factor on terahertz absorption (A), transmittance (T), and reflectance (R) for slabs of PhC that comprise rods made of GaAs, a polar dielectric, is studied. The main goal was to ... -
One-way transmission through the subwavelength slit in nonsymmetric metallic gratings
(Optical Society of America, 2010-07-27)An approach for obtaining one-way transmission in the beaming regime is suggested that is based on the directional radiation of surface plasmons in nonsymmetric metallic gratings with a single slit. In contrast to the ... -
Resonances in the electromagnetic scattering by very large finite-periodic grids of circular dielectric wires
(IEEE, 2010-06)Diffraction of plane waves by infinite gratings is a classical research topic in the scattering theory. Using the Floquet theorem, one can reduce the infinite grating problem to the one-period problem. A characteristic ... -
Spoof-plasmon relevant one-way collimation and multiplexing at beaming from a slit in metallic grating
(Optical Society of America, 2012)Diode and collimator/multiplexer functions are suggested to be combined in one device that is based on a thin metallic grating with a single subwavelength slit. A proper choice of the structural (a)symmetry of the grating ... -
Triangular metallic gratings for large absorption enhancement in thin film Si solar cells
(Optical Society of American (OSA), 2012)We estimate high optical absorption in silicon thin film photovoltaic devices using triangular corrugations on the back metallic contact. We computationally show 21.9% overall absorptivity in a 100-nmthick silicon layer, ... -
Two-dimensional ferroelectric photonic crystals: Optics and band structure
(Taylor & Francis Inc., 2013-09-20)In this report we present an investigation of the optical properties and band structure calculations for the photonic structures based on the functional materials- ferroelectrics. A theoretical approach to the optical ...
