Beaskoetxea Gartzia, Unai ; Beruete Díaz, Miguel ; Rodríguez Ulibarri, Pablo ; Etayo Salinas, David ; Sorolla Ayza, Mario ; Navarro Cía, Miguel ; Zehar, Mokhtar; Blary, Karine; Chahadih, Abdallah; Han, Xiang-Lei; Akalin, Tahsin (IEEE, 2014) Contribución a congreso / Biltzarrerako ekarpenaIn this work, a 0.566THz flat leaky-wave antenna, consisting of a central λ0/2 slot surrounded by straight parallel wedge corrugations, is numerically and experimentally analyzed. Simulations show a moderately high gain ... -
Mapping the conductivity of graphene with electrical resistance tomography
Cultrera, Alessandro; Serazio, Danilo; Zurutuza, Amaia; Centeno, Alba; Txoperena, Ohiana; Etayo Salinas, David ; Cordón, Álvaro; Redo Sánchez, Albert; Arnedo Gil, Israel ; Ortolano, Massimo; Callegaro, Luca (Nature Research, 2019) Artículo / ArtikuluaElectronic applications of large-area graphene films require rapid and accurate methods to map their electrical properties. Here we present the first electrical resistance tomography (ERT) measurements on large-area graphene ... -
New developments in the THz field for imaging applications
Con esta tesis se pretende avanzar en el desarrollo de la tecnología de terahercios (THz) dentro del campo de las aplicaciones de imagen. Actualmente, los THz se presentan como un rango frecuencial muy interesante para ...
