    • On the performance of an ENZ-based sensor using transmission line theory and effective medium approach 

      Pacheco-Peña, Víctor Upna; Beruete Díaz, Miguel Upna; Rodríguez Ulibarri, Pablo Upna; Engheta, Nader (IOP Publishing, 2019)   Artículo / Artikulua  OpenAccess
      In this paper we perform an in-depth theoretical studyofa sensing platform based on epsilon-near- zero (ENZ) metamaterials. The structure proposed for sensing is a narrow metallic waveguide channel. An equivalent circuit ...
    • Structural dispersion-based reduction of loss in epsilon-near-zero and surface plasmon polariton waves 

      Li, Yue; Liberal Olleta, Íñigo Upna; Engheta, Nader (American Association for the Advancement of Science, 2019)   Artículo / Artikulua  OpenAccess
      The field of plasmonics has substantially affected the study of light-matter interactions at the subwavelength scale. However, dissipation losses still remain an inevitable obstacle in the development of plasmonic-based ...
    • Substrate-integrated photonic doping for near-zero-index devices 

      Zhou, Ziheng; Li, Yue; Li, Hao; Sun, Wangyu; Liberal Olleta, Íñigo Upna; Engheta, Nader (Nature Research, 2019)   Artículo / Artikulua  OpenAccess
      Near-zero-index (NZI) media, a medium with near zero permittivity and/or permeability, exhibits unique wave phenomena and exciting potential for multiple applications. However, previous proof-of-concept realizations of NZI ...
