Plasmon and grid resonances in the electromagnetic scattering by finite grids of silver nanowires
Natarov, D. M.; Benson, T. M.; Altıntaş, Ayhan; Sauleau, R.; Nosich, A. I. (IEEE, 2010)The problem of the Hpolarized wave scattering by finite chains of circular nanowires is considered. A twodimensional diffraction problem with rigorous boundary conditions is solved by partial separations of variables ... 
Radar crosssection study of cylindrical cavitybacked apertures with outer or inner material coating: the case of Epolarization
Çolak, D.; Nosich, A. I.; Altintaş, A. (IEEE, 1993)A dualseriesbased solution is obtained for the scattering of an Epolarized plane wave from a cavitybacked aperture which is formed by a slitted infinite circular cylinder coated with absorbing material. The material ... 
Radar crosssection study of cylindrical cavitybacked apertures with outer or inner material coating: the case of Hpolarization
Çolak, D.; Nosich, A. I.; Altıntaş, A. (Institute of Electrical and Electronics Engineers, 199505)A dualseriesbased solution is obtained for the scattering of an Hpolarized plane wave from a slitted infinite circular cylinder coated with absorbing material from inside or outside. For both cases, numerical results ... 
Radiation characteristics of a 2D parabolic reflector antenna excited by the Hpolarized complex source
Oğuzer, T.; Nosich, A. I.; Altıntaş, Ayhan (IEEE, 200209)The aim of this paper is to obtain accurate reference data for relatively large and realistic reflector antenna systems. We concentrate on a parabolic reflector antenna in the Hpolarization case. The directive primary ... 
RCS study of cylindrical cavitybacked apertures with outer or inner material coating: the case of epolarization
Çolak, Dilek; Altıntaş, Ayhan; Nosich, A. I. (IEEE, 1993)Cavitybacked apertures (CBA) are encountered as parts of any airborne or spaceborne radar targets. Most familiar of them are, probably, air inlets and engine tubes, known to contribute a great deal to radar cross section ... 
Resonance lens antenna analysis for MMwave applications
Boriskin, A. V.; Nosich, A. I.; Boriskina, S. V.; Sewell, P.; Benson, T. M.; Altıntaş, Ayhan (IEEE, 200406)We report what is to our knowledge the first accurate theoretical investigation of the electromagnetic behavior of 2D elliptical lenses of finite wavelengthscale size. The role of internal resonances in the focal domain ... 
Simulating a wavelengthsize 2D lens with an accurate numerical method
Boriskin, A. V.; Nosich, A. I.; Altıntaş, Ayhan (IEEE, 2001)The effect of a localized light source directivity improvement due to an arbitrarily shaped dielectric cylinder taken as a 2D model of a dielectric lens is studied. The source is simulated by the field of a complex ... 
Test of accuracy of the generalized boundary conditions in the scattering by thin dielectric strips
Nosich, A. I.; Shapoval, O. V.; Sukharevsky, Ilya O.; Altıntaş, Ayhan (IEEE, 201405)The twodimensional (2D) scattering of the E and Hpolarized plane electromagnetic waves by a freestanding thinner than the wavelength dielectric strip is considered numerically. Two methods are compared: singular integral ... 
Validity and limitations of the medianline integral equation technique in the scattering by material strips of subwavellength thickness
Sukharevsky, Ilya O.; Shapoval, O. V.; Altıntaş, Ayhan; Nosich, A. I. (Institute of Electrical and Electronics Engineers, 201407)Considered is the 2D scattering of a plane wave by a thin flat material strip. The data obtained by using the empirical method of generalized boundary conditions and singular integral equations on the strip median line ... 
Wave scattering by one and many thin material strips: singular integral equations, Meshless Nystrom discretization, and periodicity caused resonances
Shapoval, O. V.; Sukharevsky, Ilya. O.; Altıntaş, Ayhan; Sauleau, R.; Nosich, A. I. (IEEE, 2014)We consider the medialline singularintegral equation technique for the analysis of the scattering by multiple thin material strips. Their discretization is performed using the Nystromtype scheme that guarantees convergence. ...
