Directional selectivity through the subwavelength slit in metallic gratings
(IEEE, 2011)An approach for obtaining strong directional selectivity through a single subwavelength slit in non-symmetric metallic gratings is shown theoretically and experimentally. Directionality effect originates from the different ... -
Enhanced transmission of microwave radiation in one-dimensional metallic gratings with subwavelength aperture
(American Institute of Physics, 2004)We report a theoretical and experimental demonstration of enhanced microwave transmission through subwavelength apertures in metallic structures with double-sided gratings. Three different types of aluminum gratings ... -
Experimental validation of strong directional selectivity in nonsymmetric metallic gratings with a subwavelength slit
(American Institute of Physics, 2011-02-02)Strong directional selectivity is theoretically predicted and experimentally validated at the microwave frequencies in the beaming regime for a single subwavelength slit in nonsymmetric metallic gratings with double-side ... -
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 ... -
Plasmonic band gap structures for surface-enhanced Raman scattering
(Optical Society of American (OSA), 2008)Surface-enhanced Raman Scattering (SERS) of rhodamine 6G (R6G) adsorbed on biharmonic metallic grating structures was studied. Biharmonic metallic gratings include two different grating components, one acting as a coupler ... -
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 ... -
Surface wave splitter based on metallic gratings with sub-wavelength aperture
(Optical Society of American (OSA), 2008)We investigated the splitting of surface electromagnetic waves trapped at the output surface of a one-dimensional metallic grating structure. The output gratings of the structure asymmetrically such that the output surfaces ... -
Triangular metallic gratings for high efficiency thin film solar cells
(IEEE, 2011)Our design of novel nanometallic structure integrated with photovoltaic devices provides polarization insensitive, broadband and significantly high absorptivity enhancement. This structure attains absorptivities higher ... -
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, ... -
Tunable surface plasmon resonance on an elastomeric substrate
(Optical Society of American (OSA), 2009-05)In this study, we demonstrate that periods of metallic gratings on elastomeric substrates can be tuned with external strain and hence are found to control the resonance condition of surface plasmon polaritons. We have ...
