Analysis of an arbitrary profile reflector antenna having resistivetype surfaceHpolarization case
(2008)A regularizationbased numerical solution is obtained for arbitraryshape conic section profile reflector antenna in 2D, for the Hpolarization case. New point is that the reflector surface is assumed a resistivetype ... 
Asymptotic wavelike modeling of dielectric lenses
(IEEE, 2007)We propose asymptotic wavelike approximations for the accurate modeling of dielectric lenses used in quasioptical systems of millimeter, submillimeter, and infrared wave applications. For the comparison, we obtain an ... 
Development of lefthanded composite materials and negative refracting photonic crystals with subwavelength focusing
(SPIE, 2005)We review the studies conducted in our group concerning electromagnetic properties of metamaterials and photonic crystals with negative effective index of refraction. In particular, we demonstate the true left handed ... 
Dimensional crossover in twodimensional BoseFermi mixtures
(Institute of Physics Publishing, 2010)We investigate the equilibrium properties of bosonfermion mixtures consisting of a Bose condensate and spinpolarized Fermi gas confined in a harmonic twodimensional (2D) trap using meanfield theory. Bosonboson and ... 
Epolarized beam scattering by an open cylindrical PEC strip having an arbitrary "conicalsection" profile
(John Wiley & Sons, Inc., 2001)Twodimensional (2D) scattering of waves by a conducting strip with a canonical profile is simulated in the Epolarization case. This analysis is performed by reducing a singular integral equation (IE) to the dualseries ... 
Effective electronelectron interactions and magnetic phase transition in a twodimensional electron liquid
(Elsevier B.V., 2007)We investigate the spindependent effective electronelectron interactions in a uniform system of twodimensional electrons to understand the spontaneous magnetization expected to occur at very low density. For this purpose, ... 
Fast and accurate computation of twodimensional nonseparable quadraticphase integrals
(Optical Society of America, 20100512)We report a fast and accurate algorithm for numerical computation of twodimensional nonseparable linear canonical transforms (2DNSLCTs). Also known as quadraticphase integrals, this class of integral transforms ... 
FDTD simulations of multiple GPR systems
(2003)A multipleGPR detection system was simulated. The main advantage of such a system was that it saves time by detecting both the transverse and the longitudinal positions of the target by a Bscan measurement, whereas the ... 
High sensitivity and multifunctional microHall sensors fabricated using InAlSb/InAsSb/InAlSb heterostructures
(2009)Further diversification of Hall sensor technology requires development of materials with high electron mobility and an ultrathin conducting layer very close to the material's surface. Here, we describe the magnetoresistive ... 
Labyrinth based lefthanded metamaterials and subwavelength focusing of electromagnetic waves
(2006)We propose and demonstrate a resonant structure that solves two major problems related to the splitring resonator structure. These major problems may be stated as the bianisotropy and electric coupling to the magnetic ... 
Landau quantization of twodimensional heavy holes, energy spectrum of magnetoexcitons and Augerrecombination lines
(2013)The Landau quantization of the twodimensional (2D) heavy holes, its influence on the energy spectrum of 2D magnetoexcitons, as well as their optical orientation are studied. The Hamiltonian of the heavy holes is written ...
