Differential Microwave Excitation Spectroscopy

In the Phase I SBIR, a novel active spectroscopic technique was investigated via laboratory experiments on various materials of interest to determine the viability of the technique for detecting materials of interest to the military, using both actual samples and appropriate simulants. This orthogonal spectroscopic technique will help resolve ambiguities when identifying a spectral signature. The Phase I results are encouraging and support the conclusion that this technique practical value. The Phase II proposal is the logical follow-on activity, providing a mechanism to more robustly investigate the phenomenon and via modeling and experimentation. The experiments expand on the Phase I results and take advantage of lessons learned so that the result of this research can support a rapid transition into field hardware.
