The objective of this project was to assess the effects of ionizing radiation on 3 classes of electromagnetic materials. The proposed approach for radiation detection was to utilize radiation-induced changes in dielectric permittivity, magnetic permeability, or electrical conductivity and monitor these changes with resonant cavities. Microwaves would be used to interrogate the device. This project resulted in 11 journal publications to date, including work on radiation-sensitive glasses, ferroelectric oxides, and various magnetic materials. This project designed and built a feedback resonator that shows high sensitivity quality factors up to 15 million and can be wirelessly monitored at stand-off distances.
