Abstract: A radiation detection device includes a plurality of field effect transistors (FETs) arranged to form a resonant cavity. The cavity includes a first end and a second end. The plurality of FETs provide an electromagnetic field defining an standing wave oscillating at a resonant frequency defined by a characteristic of the cavity. A radiation input passing through the cavity induces a perturbation of the electromagnetic field.

Abstract: A mid-wave infrared system provides high spatial and temporal resolution measurements of atmospheric temperatures and moisture fields using a constellation of low earth orbit satellites. The disclosed system is smaller, lighter, less complex, and requires less energy than existing systems, due to implementation of an infrared avalanche photodiode array detector that provides enhanced sensitivity with reduced cooling requirements, and an Offner spectrometer having a novel a refractive element inserted near the grating that reduces the size and power requirements of the spectrometer. Embodiments of the disclosed method include deploying a constellation of devices for cooperative infrared sensing of atmospheric phenomena at similar rates, lower cost, and much higher resolution compared to geosynchronous approaches. Some embodiments further include combined analysis of measurements obtained by the disclosed devices with complementary measurements made by other low-earth and high-earth orbital and/or ground-based devices.

Abstract: A MEMS device includes a bolometer attached to a silicon wafer by a base portion of at least one anchor structure. The base portion comprises a layer stack having a metal-insulator-metal (MIM) configuration such that the base portion acts as a resistive switch such that, when the first DC voltage is applied to the patterned conductive layer, the base portion transitions from a high resistive state to a low resistive state, and, when the second DC voltage is applied to the patterned conductive layer, the base portion transitions from a high resistive state to a low resistive state.
