    • Electromagnetic cloaking with canonical spiral inclusions 

      Guven, K.; Sáenz Sáinz, Elena Upna; Gonzalo García, Ramón Upna Orcid; 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 ...
    • Least upper bounds of the powers extracted and scattered by bi-anisotropic particles 

      Liberal Olleta, Íñigo Upna Orcid; Ra'di, Younes; Gonzalo García, Ramón Upna Orcid; Ederra Urzainqui, Íñigo Upna Orcid; Tretyakov, Sergei A.; Ziolkowski, Richard W. (IEEE, 2014)   Artículo / Artikulua  OpenAccess
      The least upper bounds of the powers extracted and scattered by bi-anisotropic particles are investigated analytically. A rigorous derivation for particles having invertible polarizability tensors is presented, and the ...
    • Low profile multi-frequency dipole antenna array based on planar meta-surfaces 

      Sáenz Sáinz, Elena Upna; Ikonen, Pekka; Gonzalo García, Ramón Upna Orcid; Ederra Urzainqui, Íñigo Upna Orcid; Tretyakov, Sergei A.; Maagt, Peter de (IEEE, 2007)   Contribución a congreso / Biltzarrerako ekarpena  OpenAccess
      In this paper, the radiation performance of a low profile multi-frequency dipole antenna array with a planar meta-surface is presented. The meta-surface consists of two closely located parallel grids of short dipoles and ...
    • Planar DNG superstrate for dipole antenna gain enhancement 

      Sáenz Sáinz, Elena Upna; Gonzalo García, Ramón Upna Orcid; Ederra Urzainqui, Íñigo Upna Orcid; Ikonen, Pekka; Tretyakov, Sergei A.; Maagt, Peter de (2007)   Contribución a congreso / Biltzarrerako ekarpena  OpenAccess
      In this paper, a volumetric double-negative (DNG) superstrate based on grids of dipoles and wires for dipole antenna applications is proposed.
