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 medial-line singular-integral equation technique for the analysis of the scattering by multiple thin material strips. Their discretization is performed using the Nystrom-type scheme that guarantees convergence. ...

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, 2014-05)

The two-dimensional (2D) scattering of the E and H-polarized plane electromagnetic waves by a free-standing thinner than the wavelength dielectric strip is considered numerically. Two methods are compared: singular integral ...

Radiation characteristics of a 2D parabolic reflector antenna excited by the H-polarized complex source

Oğuzer, T.; Nosich, A. I.; Altıntaş, Ayhan (IEEE, 2002-09)

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 H-polarization case. The directive primary ...

Resonance lens antenna analysis for MM-wave applications

Boriskin, A. V.; Nosich, A. I.; Boriskina, S. V.; Sewell, P.; Benson, T. M.; Altıntaş, Ayhan (IEEE, 2004-06)

We report what is to our knowledge the first accurate theoretical investigation of the electromagnetic behavior of 2-D elliptical lenses of finite wavelength-scale size. The role of internal resonances in the focal domain ...
