Analysis of radome covered circular reflectors by complex source-dual series approach
(IEEE, 1994)Radiation from a two dimensional reflector antenna covered by a cylindrical radome is analyzed by the complex dual series approach. It is only performed for the electrically polarized incident field. The approach is based ... -
Circular arrays of log-periodic antennas for broadband applications
(IEEE, 2006)Circular arrays of log-periodic (LP) antennas are designed for broadband applications. A sophisticated electromagnetic simulation environment involving integral equations and fast solvers is developed to analyze the LP ... -
Electric field effects on optical properties of semiconductor nanorods
(2009-05)We studied electric field effects on optical properties of CdSe/ZnS nanorods integrated in thin films sandwiched between transparent electrodes. It was demonstrated that P-polarized component of the photoluminescence of ... -
Electron initiated impact ionization in AlGaN alloys
(Institute of Physics, 2002)Detailed impact ionization (II) analysis of electrons is presented for AlGaN alloys as a vital resource for solar-blind avalanche photodiode and high power transistor applications. Necessary ingredients for the II ... -
Electronic structure of the contact between carbon nanotube and metal electrodes
(American Institute of Physics, 2003)Our first-principles study of the contact between a semiconducting single-walled carbon nanotube ~s-SWNT! and metal electrodes shows that the electronic structure and potential depend strongly on the type of metal. The ... -
Electronic transport through a kink in an electron waveguide
(Institute of Electrical and Electronics Engineers, 1994)The current-voltage denendence correspondinp to electronic transport through a kink in an electronic waveguide is analyzed. No phase breaking dissipation mechanisms are considered, but the effects of the Coulomb interaction ... -
Energy-transfer rate in a double-quantum-well system due to Coulomb coupling
(Elsevier, 2002)We study the energy-transfer rate for electrons in a double-quantum-well structure, where the layers are coupled through screened Coulomb interactions. The energy-transfer rate between the layers (similar to the Coulomb ... -
Guiding and bending of photons via hopping in three-dimensional photonic crystals
(IEEE, Piscataway, NJ, United States, 2000)For the past decade, photonic crystals, also known as photonic bandgap (PBG) materials, have inspired great interest because of their novel scientific and engineering applications such as the inhibition of spontaneous ... -
Highly directional enhanced radiation from sources embedded inside two and three-dimensional photonic crystals
(SPIE, 2005)In this work, we have experimentally and theoretically studied the emission of radiation from a monopole source embedded in a two and three dimensional photonic crystal. We have demonstrated the enhancement of radiation ... -
Incomplete LU preconditioning for the electric-field integral equation
(, 2006)Linear systems resulting from the electric-field integral equation (EFIE) become ill-conditioned, particularly for large-scale problems. Hence, effective preconditioners should be used to obtain the iterative solution with ... -
Investigation of the inaccuracy of the MFIE discretized with the RWG basis functions
(IEEE, 2004-06)The inaccuracy of the magnetic-field integral equation (MFIE) discretized with the Rao-Wilton-Glisson (RWG) basis functions is discussed. The electric-field integral equation (EFIE) gives accurate results with the usage ... -
Magnetic and electric Aharonov-Bohm effects in nanostructures
(Elsevier BV, 1996)The paper reviews and extends the magnetic Aharonov-Bohm effect (persistent current, resistance oscillation) in normal-metal rings including spin-independent and spin-dependent hopping, Zeeman splitting, magnetic textures ... -
Orientational transition and complexation of DNA with anionic membranes: weak and intermediate electrostatic coupling
(American Physical Society, 2019)We characterize the role of charge correlations in the adsorption of a short, rodlike anionic polyelectrolyte onto a similarly charged membrane. Our theory reveals two different mechanisms driving the like-charge ... -
Photonic band gap effect and localization in two-dimensional Penrose lattice
(IEEE, 2001)A study of photonic bandgap effect and localization in two-dimensional Penrose lattice was performed. Penrose quasicrystals consisted of dielectric rods and defect characteristics of various inequivalent sites of the crystal ... -
Thermomagnetic effects of nondegenerate Kane semiconductors under the conditions of mutual electron-phonon drag in high electric and arbitrary magnetic fields
(2005)The thermopower and Nernst-Ettingshausen (NE) effect of nondegenerate Kane semiconductors are investigated by taking into account the electron and phonon heating and their arbitrary mutual drag. The electron spectrum is ...
