Decoupling of multifrequency dipole antenna arrays for microwave imaging applications
Sáenz Sáinz, Elena; Guven, K.; Ozbay, Ekmel; Ederra Urzainqui, Íñigo
; Gonzalo García, Ramón
(Hindawi Publishing Corporation, 2010) Artículo / Artikulua
The mutual coupling between elements of a multifrequency dipole antenna array is experimentally investigated by S-parameter measurements and planar near-field scanning of the radiated field. A multifrequency array with ... -
Electromagnetic cloaking with canonical spiral inclusions
Guven, K.; Sáenz Sáinz, Elena; Gonzalo García, Ramón
; Ozbay, Ekmel; Tretyakov, Sergei A. (IOP Publishing Ltd., 2008) Artículo / Artikulua
We report an electromagnetic cloaking structure that is composed of identical canonical spiral particles. By using the Clausius-Mosotti formula, the electric and magnetic polarizabilities of a single spiral particle are ... -
Multiband one-way polarization conversion in complementary split-ring resonator based structures by combining chirality and tunneling
Serebryannikov, Andriy E.; Beruete Díaz, Miguel; Mutlu, Mehmet; Ozbay, Ekmel (Optical Society of America, 2015) Artículo / Artikulua
Multiband one-way polarization conversion and strong asymmetry in transmission inspired by it are demonstrated in ultrathin sandwiched structures that comprise two twisted aperture-type arrays of complementary split-ring ... -
Tunable deflection and asymmetric transmission of THz waves using a thin slab of graphene-dielectric metamaterial, with and without ENZ components
Serebryannikov, Andriy E.; Hajian, Hodjat; Beruete Díaz, Miguel; Ozbay, Ekmel; Vandenbosch, Guy A. E. (Optical Society of America, 2018) Artículo / Artikulua
Tunable deflection of obliquely incident, linearly polarized terahertz waves is theoretically studied in a wide frequency range around 20 THz, by combining a thin slab of graphene-dielectric metamaterial (with ten layers ...
