Dielectric properties of comet analog refractory materials
摘要
Ground penetrating radio waves or radar provide a promising technique for the study of sub-surface planetary or cometary material. The comet nucleus sounding experiment by radiowave transmission (CONSERT) will be the only experiment on board the ROSETTA mission to provide information on the interior of the comet Wirtanen. Other projects planned or under development are Marsis/Mars Express and GPR for Net Lander. The aim is to perform a radar tomography, and the necessary data inversion of the measured permittivity requires knowledge of the complex dielectric permittivities of probable sub-surface materials, so laboratory studies of the dielectric properties of analog geological materials have become necessary.
