Description

This research opportunity involves the development of new concepts and numerical techniques to estimate and characterize scattering and emission from various constituent of inhomegeous media and develop appropriate methods to extract information about the individual component of the media. For this opportunity exploring methods to estimate fully polarimeteric scattering model of composite media will be of interest for space borne SAR technology. For NASA's landed missions (where a space craft will be in touch with planatary surface) development of proximity sensors such as Capacitance/Inductance Tomography is essential. This opportunity solicits new ideas/concepts to design and analyze Capacitance/Inductance sensors to be mounted on future space craft. NASA in its future missions invisions use of submillimeter (200 GHz~ 800GHz) technology for atmospheric probing. The experimetal testing of electrically large antennas used in these missions is problematic due to limited size of the compact anechoic chambers. Under this opportunity new ideas/concepts to measure performance of electrically large antennas are also welcomed.
