    • Direct observation of ideal electromagnetic fluids 

      Li, Hao; Zhou, Ziheng; Sun, Wangyu; Lobet, Michaël; Engheta, Nader; Liberal Olleta, Íñigo Upna Orcid; Li, Yue (Springer Nature, 2022)   Artículo / Artikulua  OpenAccess
      Near-zero-index (NZI) media have been theoretically identified as media where electromagnetic radiations behave like ideal electromagnetic fluids. Within NZI media, the electromagnetic power flow obeys equations similar ...
    • Fundamental radiative processes in near-zero-index media of various dimensionalities 

      Lobet, Michaël; Liberal Olleta, Íñigo Upna Orcid; Knall, Erik N.; Alam, M. Zahirul; Reshef, Orad (American Chemical Society, 2020)   Artículo / Artikulua  OpenAccess
      Spontaneous emission, stimulated emission and absorption are the three fundamental radiative processes describing light-matter interactions. Here, we theoretically study the behavior of these fundamental processes inside ...
    • Momentum considerations inside near-zero index materials 

      Lobet, Michaël; Liberal Olleta, Íñigo Upna Orcid; Vertchenko, Larissa; Lavrinenko, Andrei V.; Engheta, Nader; Mazur, Eric (Springer Nature, 2022)   Artículo / Artikulua  OpenAccess
      Near-zero index (NZI) materials, i.e., materials having a phase refractive index close to zero, are known to enhance or inhibit light-matter interactions. Most theoretical derivations of fundamental radiative processes ...
    • Near-zero-index media as electromagnetic ideal fluids 

      Liberal Olleta, Íñigo Upna Orcid; Lobet, Michaël; Li, Yue; Engheta, Nader (National Academy of Sciences, 2020)   Artículo / Artikulua  OpenAccess
      Near-zero-index (NZI) supercoupling, the transmission of electromagnetic waves inside a waveguide irrespective of its shape, is a counterintuitive wave effect that finds applications in optical interconnects and engineering ...
    • Tutorial on the conservation of momentum in photonic time-varying media [Invited] 

      Ortega Gómez, Ángel; Lobet, Michaël; Vázquez Lozano, Juan Enrique; Liberal Olleta, Íñigo Upna Orcid (Optica, 2023)   Artículo / Artikulua  OpenAccess
      Time-varying media break temporal symmetries while preserving spatial symmetries intact. Thus, it represents an excellent conceptual framework to investigate the fundamental implications of Noether’s theorem for the ...
