Antireflection coating at metamaterial waveguide structures for solar energy applications
(Elsevier, 2014)The optical reflection properties of a periodic metamaterial-dielectric multilayered structure are investigated theoretically. The structure is an antireflection coating if it is placed between two semi-infinite media of ... -
Calculation of reflected and transmitted powers of a metamaterial waveguide structure using MAPLE software
(Optical Society of America, 2013)Consider a waveguide structure consisting of a pair of metamaterial and dielectric slabs inserted in vacuum. A plane polarized wave is obliquely incident on it. Metamaterials (sometimes termed left-handed materials (LHMs)) ... -
Characterization of PVK Polymeric Material Using Rotating Polarizer and Analyzer Ellipsometer with a Speed Ratio 1
(2016)A homemade spectroscopic ellipsometer is designed indigenously to characterize Si-SiO2 sample and two Poly (9-vinylcarbazole)(PVK) films. In the constructed ellipsometer, the polarizer and analyzer rotate in the same ... -
Highly Efficient Solar Energy Conversion Using Graded-index Metamaterial Nanostructured Waveguide
(2020)In this paper, a graded-index metamaterial (GIM) nanostructured waveguide is proposed to enhance the performance of solar cells via a tunable absorption spectrum. The proposed four-layer nanostructured waveguide consists ...
