    • Generation of lossy mode resonances by deposition of high-refractive-index coatings on uncladded multimode optical fibers 

      Del Villar, Ignacio Upna; Ruiz Zamarreño, Carlos Upna; Sánchez Zábal, Pedro Upna; Hernáez Sáenz de Zaitigui, Miguel Upna; Fernández Valdivielso, Carlos Upna; Arregui San Martín, Francisco Javier Upna; Matías Maestro, Ignacio Upna (IOP Publishing Ltd, 2010)   Artículo / Artikulua  OpenAccess
      A comparative study of lossy mode resonances generated by depositing two different materials is presented. The two materials selected are indium tin oxide (ITO) and indium oxide. The two materials present different ...
    • On the nonlinear stability of the triangular points in the circular spatial restricted three-body problem 

      Cárcamo Díaz, Daniela Jacqueline; Palacián Subiela, Jesús Francisco Upna; Vidal Díaz, Claudio; Yanguas Sayas, Patricia Upna (Pleiades Publishing, 2020)   Artículo / Artikulua  OpenAccess
      The well-known problem of the nonlinear stability of L4 and L5 in the circular spatial restricted three-body problem is revisited. Some new results in the light of the concept of Lie (formal) stability are presented. In ...
