We propose a metamaterial-enhanced microbolometer with strong absorption over a narrow band that is dynamically tunable over the 8-10 micron band. A single-layer photonic metamaterial consisting of a thin metal film perforated with a 2-D array of dielectric apertures will be deposited on an amorphous-Silicon layer acting as an absorber and bolometer. The metamaterial, in conjunction with planar di ...

This topic addresses the need for compact efficient solid-state deep ultraviolet (UV) lasers operating in the wavelength range of 220-250 nm, for use in Raman systems for chemical and biological detection. The laser to be developed would also be very useful in the detection of explosives. We propose to develop an efficient 946 Q-switched nm laser system that is efficiently quadrupled to 236.5 nm. ...

There is a market need for high intensity sound sources that can operate for long durations over wide temperature ranges and in environments with dust and humidity exposure. Piezoelectric sound sources offer many advantages over compression drivers in these applications. They can be small and lightweight, have low power consumption, operate in narrow frequency bands, and can achieve a high sound p ...

KCF Technologies proposes to develop a robust and efficient sound generator for separation/isolation of aerosols. The critical limitations in the performance of conventional piezoelectric sound generators include degradation in performance over long periods of operation, poor electro-acoustic efficiencies at high amplitude drive levels, and large tolerances in their acoustic performance. These pro ...

Currently, the accepted standard experimental model for measuring protective efficacy against botulism is the Mouse Lethality Neutralization (MLN) assay. Botulism poisoning is a life threatening condition that is not only a public health concern, but could also be a potential biological weapon. With seven serotypes of botulinum neurotoxins, there is need for an alternative to the MLN assay due t ...

Organophosphorus chemical warfare nerve agents (OP-CWA) are attractive to terrorist groups and rogue states as an inexpensive and accessible technology for chemical warfare. OP-CWA and organophosphate pesticides cause severe neurological symptoms and death by inhibiting the enzyme acetylcholinesterase (AChE); the resulting excess acetylcholine accumulates and overstimulates the human or animal bo ...
