Compact pillbox reflector based on geodesic lens
Pérez Quintana, Dayan; Chen, Q.; Beruete Díaz, Miguel
; Quevedo-Teruel, O. (IEEE, 2022)
Contribución a congreso / Biltzarrerako ekarpena 
We propose a pillbox antenna in combination with a geodesic lens at 60 GHz. The antenna is implemented in a dual-layer parallel plate waveguide. The waves from a geodesic lens in a first layer, after being reflected by a ... -
Design of multi-layered radiative cooling structures using evolutionary algorithms
Lezaun Capdevila, Carlos; Jorajuría, Tania; Torres García, Alicia E. ; Herrera, Pilar; Beruete Díaz, Miguel (IEEE, 2022)
Contribución a congreso / Biltzarrerako ekarpena
In this work we present a novel way to design thinfilm radiative cooling metamaterials based on genetic algorithms. Three simulations with different design constraints have been done, resulting in three structures that ... -
Enhancing the infrared and visible emission properties of calcium silicate hydrate for radiative cooling using metamaterials
Lezaun Capdevila, Carlos; Dolado, J. S.; Torres García, Alicia E. ; Pérez Escudero, José Manuel ; Liberal Olleta, Íñigo ; Beruete Díaz, Miguel (IEEE, 2022)
Contribución a congreso / Biltzarrerako ekarpena
Two periodic structures composed of metal cylinders with different orientations are used to improve the solar reflection of calcium silicate hydrate (CSH) while maintaining its atmospheric emission. Interesting effects ... -
Hyperbolic lens antenna in groove gap waveguide technology at sub-millimeter waves
Pérez Quintana, Dayan; Biurrun Quel, Carlos ; Ederra Urzainqui, Íñigo ; González-Ovejero, David; Beruete Díaz, Miguel (IEEE, 2022)
Contribución a congreso / Biltzarrerako ekarpena
In this paper, a flat hyperbolic lens antenna using Groove Gap Waveguide (GGW) technology is designed at 300 GHz. A GGW horn antenna is used to feed the metamaterial lens placed in a parallel plate waveguide (PPW), in order ...
