    Soil permittivity estimation using Polarimetric Synthetic Aperture Radar (PolSAR) data has been an extensively researched area. Nonetheless, it provides ample scope for further improvements. The vegetation cover over the ...
  • Two-dimensional Thouless pumping of light in photonic moiré lattices 

    Wang, Peng; Fu, Qidong; Peng, Ruihan; Kartashov, Yaroslav V.; Torner Sabata, Lluís; Konotop, Vladimir V.; Ye, Fangwei (2022-11-08)
    Article
    Open Access
    Continuous and quantized transports are profoundly different. The latter is determined by the global rather than local properties of a system, it exhibits unique topological features, and its ubiquitous nature causes its ...
  • Updated BVD modeling of AlN-based solidly mounted resonators working at cryogenic and high temperatures: from -160°C up to 130°C 

    Lugo Hernández, Eduardo; Collado Gómez, Juan Carlos; Mateu Mateu, Jordi; Carmona Cejas, José Manuel; Mirea, Teona; Olivares Roza, Jimena (Institute of Electrical and Electronics Engineers (IEEE), 2022)
    Conference lecture
    Open Access
    In this work we theoretically and experimentally assess the behavior of AlN-based Solidly Mounted Resonators (SMR) at cryogenic and high temperatures. This study can be useful for precise behavior prediction of SMR sensors ...
  • Orbit design for a satellite swarm-based Motion Induced Synthetic Aperture Radiometer (MISAR) in low-earth orbit for earth observation applications 

    Lützner, Mark; Jagdhuber, Thomas; Camps Carmona, Adriano José; Hyuk, Park; Peichl, Markus; Förstner, Roger; Jirousek, Matthias (Institute of Electrical and Electronics Engineers (IEEE), 2022)
    Article
