Contribución a congreso / Biltzarrerako ekarpena
In this work, a Bull's-Eye (BE) antenna with circular polarization (CP) based on ridge gap waveguide (RGW) technology, working in the millimeter-wave band (60 GHz) is numerically and experimentally demonstrated. The structure ... -
Comparison of a slotted SIW antenna covered with metasurface vs. a traditional array
Chocarro Álvarez, Javier; Pérez Escudero, José Manuel ; Ederra Urzainqui, Íñigo (IEEE, 2022)
Contribución a congreso / Biltzarrerako ekarpena
In this article we compare two solutions to improve the radiation pattern of a slotted Substrate Integrated Waveguide (SIW) antenna: use of an E-plane array and covering it with a metasurface (MTS). To this aim, we compare ... -
Comparison of modified Soret lenses for dual band integrated detectors

Contribución a congreso / Biltzarrerako ekarpena
This work presents a new topology of a Coherently Radiating Periodic Structure - Beam Forming Network (CORPS-BFN) and its application for multibeam systems. A unit cell, consisting of a transition from a coaxial input to ... -
Performance evaluation of spatial modulation patterns in compressive sensing terahertz imaging
Ndagijimana, Adolphe; Heredia Conde, Miguel; Ederra Urzainqui, Íñigo (IEEE, 2022)
Contribución a congreso / Biltzarrerako ekarpena
Terahertz (THz) imaging traditionally uses pixel-to-pixel mechanical raster scanning, which is slow and limits the resolution and potential applications. Compressive Sensing Terahertz (CS-THz) imaging has the potential to ...
