    • Decoupling of multifrequency dipole antenna arrays for microwave imaging applications 

      Sáenz Sáinz, Elena Upna; Guven, K.; Ozbay, Ekmel; Ederra Urzainqui, Íñigo Upna; Gonzalo García, Ramón Upna (Hindawi Publishing Corporation, 2010)   Artículo / Artikulua  OpenAccess
      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 Upna; Gonzalo García, Ramón Upna; Ozbay, Ekmel; Tretyakov, Sergei A. (IOP Publishing Ltd., 2008)   Artículo / Artikulua  OpenAccess
      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 Upna; Mutlu, Mehmet; Ozbay, Ekmel (Optical Society of America, 2015)   Artículo / Artikulua  OpenAccess
      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 ...
