In this Phase II program, improved performance SWIR sensors with extended wavelength response to 2.5 microns will be developed using two disruptive technologies, which Amethyst has successfully demonstrated in the Phase I program: unipolar barrier (e.g., nBn) detector structures, and defect passivation via hydrogenation. This two-pronged approach addresses the main performance limitation of extend ...

Improved performance SWIR sensors with extended wavelength response to 2.5 microns will be developed using two disruptive technologies with which Amethyst has demonstrated success: nBn detector structures and defect passivation via hydrogenation. Similar to conventional extended wavelength photodiodes, the improved sensors will based on mismatched InGaAs grown on graded buffer layers on InP substr ...

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 ...

Short range line-of-site communication is an integral part of the SOF mission. In nearly all regions where SOF operations take place, there is little if any short-range line-of-site communications infrastructure that can support these missions. The objective of this project is to design and eventually build a small (less that 64 cubic inches, targeted) lightweight (less than 1 lb. targeted), man ...

Nomadics will undertake the development of a reduced footprint life support monitor for use in far-forward battle environments. Existing systems are bulky and weight constrained causing their ineffectiveness in scenarios where the warfighter is woundedand requires acute medical attention in a timely manner. The proposed system will rely on advancements being made to acute care medical sensors th ...

"To be effective, communications used by warfighters must be able to reach its destination without detection or interception by hostile forces. The system must provide multiple modes of operations that can be easily changed to support different operationalarenas and to adapt their communications methods to external threats. Nomadics proposes to design such a system, ready for integration into Jo ...
