    • A Chebyshev transformer-based microstri-to-groove-gap-waveguide inline transition for MMIC packaging 

      Pérez Escudero, José Manuel Upna Orcid; Torres García, Alicia E. Upna Orcid; Gonzalo García, Ramón Upna Orcid; Ederra Urzainqui, Íñigo Upna Orcid (IEEE, 2019)   Artículo / Artikulua  OpenAccess
      The gap waveguide technology has become an alternative to millimeter- and submillimeter-wave electronic circuit packaging thanks to the loss reduction associated with its use. In this paper, a simplified design of an inline ...

    • Compact groove diamond antenna in gap waveguide technology with broadband circular polarization at millimeter waves 

      Pérez Quintana, Dayan Upna Orcid; Torres García, Alicia E. Upna Orcid; Ederra Urzainqui, Íñigo Upna Orcid; Beruete Díaz, Miguel Upna Orcid (IEEE, 2020)   Artículo / Artikulua  OpenAccess
      In this paper, three compact antennas using the Ridge Gap Waveguide (RGW) technology working in the millimeter-wave band (60 GHz), with a high-purity and broadband circular polarization (CP) are numerically and experimentally ...

    • A gap waveguide-based compact rectangular waveguide to a packaged microstrip inline transition 

      Pérez Escudero, José Manuel Upna Orcid; Torres García, Alicia E. Upna Orcid; Gonzalo García, Ramón Upna Orcid; Ederra Urzainqui, Íñigo Upna Orcid (MDPI, 2020)   Artículo / Artikulua  OpenAccess
      In this paper two different simple to design and easy to manufacturing transitions from a microstrip to rectangular waveguide based on ridge and groove gap waveguides are studied. The first one is based on a combination ...

    • Ku band low profile asymmetric Bull’s-Eye antenna with reduced side lobes and monopole feeding 

      Beaskoetxea Gartzia, Unai Upna Orcid; Torres García, Alicia E. Upna Orcid; Beruete Díaz, Miguel Upna Orcid (IEEE, 2018)   Artículo / Artikulua  OpenAccess
      In this paper, a linearly polarized low profile and asymmetric Bull’s-Eye leaky wave antenna fed by a monopole operating at 13 GHz is presented. Broadside radiation from the monopole is achieved by surrounding it with an ...

    • Metal-free design of a multilayered metamaterial with chirped Bragg grating for enhanced radiative cooling 

      Osuna Ruiz, David; Lezaun Capdevila, Carlos; Torres García, Alicia E. Upna Orcid; Beruete Díaz, Miguel Upna Orcid (Optica, 2023)   Artículo / Artikulua  OpenAccess
      A wideband, all-dielectric metamaterial structure for enhancing radiative cooling is investigated. The structure is optimized to reflect most of the solar irradiance window (between 0.3 µm–3 µm), which is one of the biggest ...

    • Modified Soret lenses for dual band integrated detectors at submillimetre and millimetre wavelengths 

      Torres García, Alicia E. Upna Orcid; Pérez Escudero, José Manuel Upna Orcid; Gonzalo García, Ramón Upna Orcid; Ederra Urzainqui, Íñigo Upna Orcid (IEEE, 2020)   Artículo / Artikulua  OpenAccess
      This paper presents a planar silicon integrated subharmonic mixer on top of a photonic-crystal platform. The local oscillator (LO) power is injected through a 2D photonic crystal (PC) slab to a resonant cavity that effectively ...

    • Silicon integrated subharmonic mixer on a photonic-crystal platform 

      Torres García, Alicia E. Upna Orcid; Pérez Escudero, José Manuel Upna Orcid; Teniente Vallinas, Jorge Upna Orcid; Gonzalo García, Ramón Upna Orcid; Ederra Urzainqui, Íñigo Upna Orcid (IEEE, 2021)   Artículo / Artikulua  OpenAccess
      This paper presents a planar silicon integrated subharmonic mixer on top of a photonic-crystal platform. The local oscillator (LO) power is injected through a 2D photoniccrystal (PC) slab to a resonant cavity that effectively ...

    • A simplified design inline microstrip-to-waveguide transition 

      Ederra Urzainqui, Íñigo Upna Orcid; Gonzalo García, Ramón Upna Orcid; Pérez Escudero, José Manuel Upna Orcid; Torres García, Alicia E. Upna Orcid (MDPI, 2018)   Artículo / Artikulua  OpenAccess
      A simplified design of an inline transition between microstrip and rectangular waveguide is presented in this paper. The transition makes use of a dielectric filled rectangular waveguide (DFRW) as an intermediate step, ...

    • Suppressed-scattering spectral windows for radiative cooling applications 

      Pérez Escudero, José Manuel Upna Orcid; Torres García, Alicia E. Upna Orcid; Lezaun Capdevila, Carlos; Caggiano, Antonio; Peralta, Ignacio; Dolado, Jorge S.; Beruete Díaz, Miguel Upna Orcid; Liberal Olleta, Íñigo Upna Orcid (Optica, 2023)   Artículo / Artikulua  OpenAccess
      The scattering of light by resonant nanoparticles is a key process for enhancing the solar reflectance in daylight radiative cooling. Here, we investigate the impact of material dispersion on the scattering performance of ...
