• 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 ...
    • Superbackscattering antenna arrays 

      Liberal Olleta, Íñigo Upna Orcid; Ederra Urzainqui, Íñigo Upna Orcid; Gonzalo García, Ramón Upna Orcid; Ziolkowski, Richard W. (IEEE, 2015)   Artículo / Artikulua  OpenAccess
      This article discusses the theory, design and practical implementation of superbackscattering antenna arrays. In analogy with Uzkov’s maximal directivity theorem, it is demonstrated that the maximal backscattering ...
    • Upper bounds on scattering processes and metamaterial-inspired structures that reach them 

      Ederra Urzainqui, Íñigo Upna Orcid; Liberal Olleta, Íñigo Upna Orcid; Gonzalo García, Ramón Upna Orcid; Ziolkowski, Richard W. (IEEE, 2014)   Artículo / Artikulua  OpenAccess
      The physical limitations on time-harmonic scattering processes are investigated on the basis of the optical theorem. Previously derived least upper bounds on the total scattering and absorption cross-sections are obtained ...
