Antenne e Sensori a Microonde

The research group is active in the study, development, and testing of microwave and millimeter-wave antennas and sensors for space and terrestrial applications. Its activities include the design of innovative antennas, particularly leaky-wave antennas; the development of advanced electromagnetic methods for antennas based on periodic structures and for the analysis of scattering from natural surfaces (soil, vegetation, ocean); and the development of algorithms for the analysis and processing of satellite data, mainly acquired through Earth-observation missions.

Multisatellite multisensor observations of a sub-plinian volcanic eruption: The 2015 calbuco explosive event in Chile

A-train satellite data, acquired during the Calbuco volcano (Chile) sub-Plinian eruption in April 2015, are discussed to explore the complementarity of spaceborne observations in the microwave (MW), thermal infrared (TIR), and visible wavelengths for both near-source plume and distal ash clouds. The analysis shows that TIR-based detection techniques are not suitable near the volcanic vent where rising convective columns are associated with large optical depths.
