This Small Business Technology Transfer (STTR) Phase I project aims at developing new material growth technology for manufacturing semiconductor substrates of cubic 3C-SiC polytype for high-power, high-frequency, high-temperature, and high-radiation hardness military, space, and commercial applications. The new process for SiC epitaxial growth utilizes novel mechanisms of gas phase and surface rea ...

A longwire antenna module is proposed, incorporating a length reduction technique that yields 25-75% length reduction with minimal impact on gain. A resonant monopole antenna operating at 535kHz is approximately 440ft long; length reduction techniques will reduce this to between 69ft and 134ft depending upon the desired gain. A shorter/lighter longwire antenna will allow the aircraft to be more ...

An antenna system is proposed for the purpose of FM, TV-VHF, and TV-UHF PSYPOS broadcast applications. The antenna system incorporates a radiating structure that is small, light weight, and conformal. A circularly polarized beam is broadcast from an aircraft towards nadir, illuminating the region below the craft with a horizontally-polarized signal, yielding polarizations pointing in both the No ...

This Small Business Technology Transfer Phase I project proposes the joint development of a compact/portable laser spectroscopic trace gas sensor based on quartz-enhanced photo-acoustic spectroscopy (QEPAS) recently demonstrated in the lab. QEPAS uses a low cost quartz tuning fork as the sensing element and provides immunity to environmental acoustic noise and enables the use of very small gas cel ...

This Small Business Technology Transfer (STTR) Phase I research project proposes to develop new methods for blue/UV laser fabrication. These new devices will have the competitive advantages of higher emission intensities, higher reliability, and ability to extend emission into the deep UV spectral range. Fabricated devices will consist of cleaved AlGaN epitaxial layer structures on the tips of cop ...

Bovine Respiratory Disease is the most costly disease among cattle arriving at feedlots and results in decreased weight gain, lower quality meat and death. BRD is highly transmittable and a rapid and sensitive diagnostic method for BRD is not currently available. This project will validate a state-of-art biomedical breath analysis sensor to assess the respiratory health of cattle. Our goal is to i ...

An important problem facing rural America is the lack of job opportunities. This is particularly true in much of the arid southwestern U.S. These rural communities have little that they can export into commodity priced markets. Hence, this region has among the highest incidence (% of county population) of poverty in the U.S. Yet, the southwestern U.S. has abundant solar energy which could provide ...

The short read range of current cattle electronic identification ear tags threatens to hinder the widespread adoption and utility of the USDA-developed National Animal Identification System (NAIS). Tag readers that require placement within inches of an animal's ear in order to read the NAIS number introduce obstacles at various points in the beef production cycle. This project will determine if be ...

This Small Business Innovation Research (SBIR) Phase I project will develop a new passivation technique, derived from a recent discovery that semiconductors can be readily hydrogenated by simultaneous exposure to hydrogen gas and ultra-violet light. The technique has a number of advantages over conventional glow discharge hydrogenation, is immediately applicable to processes requiring selective a ...
