Abstract

The objective of this Small Business Technology Transfer (STTR) project is to develop a prototype compact, portable electro-optic EM/thermal imaging system. The proposed electromagnetic/thermal imaging system can be directly utilized for the characterization of various RF structures including complex integrated circuits and large-scale antenna arrays. It provides near-field and thermal profiles of RF structures with an unprecedented high resolution and a measurement bandwidth over 100GHz. In the Phase I feasibility study, the capability of combined EM and thermal imaging will be demonstrated based on the existing electro-optic imaging system developed at the University of Michigan. A fiber-based laser will be integrated as an optical source into the system to make it compact and portable.The proposed electromagnetic/thermal imaging system can be utilized from the early design stage to the final performance validation of various FR structures for military and industry applications including large-scale high-density integrated circuits and active arrays.
