Caractérisation électromagnétique de matériaux non usinables. Application a l'étude d'éclats de météorites
National audience Radiometric measurements in microwave frequency range and submillimeter have been performed on an asteroid, S. Gulkis (JPL) and the team MIRO (Microwave Instrument on the orbiter of the spacecraft Rosetta comet), will study the physicochemical characteristics of this asteroid. Howe...
