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)) ... -
Effect of dissipation factor on reflected and transmitted powers of a structure containing left-handed material waveguide
(SciPress Ltd, 2013)EN In this paper a waveguide structure consisting of a pair of left-handed material (LHM) and dielectric slabs inserted in vacuum is investigated theoretically. Two cases of the LHM are considered, loss-less case and loss ... -
Effect of negative permittivity and permeability on the transmission of electromagnetic waves through a structure containing left-handed material
(Scientific Research Publishing, 2011)We investigate the characteristics of electromagnetic wave reflection and transmission by multilayered structures consisting of a pair of left-handed material (LHM) and dielectric slabs inserted between two semi-infinite ... -
Maximum and minimum transmittance of a structure containing N identical pairs of left-and right-handed materials
(IEEE, 2012)The optical transmission properties of a waveguide structure consisting of N identical pairs of left- and right-materials are investigated theoretically. The Expressions of the reflectance and transmittance are given in ... -
Modeling the Effect of Electromagnetic Waves Produced by Mobile Phone Base Station on human body Tissue
(2010-10)In this work, we studied the effect of electromagnetic radiation produced from mobile phone at 900 MHz frequency on the human body tissues. We modeled human body tissue by four layered system to represent skin-fat-muscles-organs ... -
Numerical study of a structure containing left-handed material waveguide
(Springer-Verlag, 2012)In this paper a waveguide structure consisting of a pair of left-handed material (LHM) and dielectric slabs inserted in vacuum is investigated theoretically. Maxwell’s equations are used to determine the electric and ... -
Numerical study of negative-refractive index ferrite waveguide
(2011)Consider a magnetized ferrite-wire waveguide structure situated between two half free spaces. Ferrites to provide negative permeability and wire arrays to provide negative permittivity. The structure form left-handed ... -
Power Density and SAR in Multi-Layered Life Tissue at Global System Mobile (GSM) Frequencies
(Published Online August 2011, 2011)In this paper, the power density and specific absorption rate (SAR) distribution in multi-layered life tissues and exposed to electromagnetic field emitted from handheld cellular phone operating in the 900 MHz and 1800 MHz ... -
Reflected and transmitted powers of electromagnetic waves through a ferrite-dielectric photonic crystal
(SciPress Ltd, 2014)EN In this work, reflection and transmission of electromagnetic wave by a periodic ferrite-dielectric photonic crystal are investigated theoretically and numerically. The ferrite material is described and its main parameters ...
