Efficient analysis of large phased arrays using iterative MoM with DFT-based acceleration algorithm

Ertürk, V. B.; Chou, H-T. (John Wiley & Sons, Inc., 2003)

A discrete Fourier transform (DFT)-based iterative method of moments (IMoM) algorithm is developed to provide an O(Ntot) computational complexity and memory storages for the efficient analysis of electromagnetic ...
Negative refraction and subwavelength focusing using left-handed composite metamaterials

Özbay, Ekmel; Aydın, Koray (SPIE, 2008-01)

We review experimental studies performed on left-handed metamaterials (LHM) at microwave frequencies. The metamaterial structure is composed of periodic arrays of split-ring resonators and wire meshes and exhibits a ...
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. ...
