"The program will demonstrate the scientific, technical and commercial merit of our innovative infrared window material and cost-effective production process. The materials will have IR transmission characteristics close to that of current monolithicsapphire and ALON window materials. Additionally, our self-reinforced single crystal oxide material will provide a substantial improvement in therma ...

"AlGaN-based heterostructures have demonstrated versatility in optical and electronic applications which is practically unmatched by other material systems. The AlGaN/GaN high electron mobility transistors (HEMTs) constitute a leading candidate forsimultaneously realizing ultra-high frequency low noise amplifiers and power amplifiers. The electron transport properties at the AlGaN/GaN interface al ...

"Current plans for high-power defense systems such as ABL and SBL, require adaptive mirrors that can handle high-power requirements, correct wavefront errors, and perform precise pointing and tracking. Normally separate devices that increase the complexityof the beam train handle these functions. Two problems must be addressed. First, high-power laser systems degrade the optical quality of thei ...

"During the past 5 years, Mentis Sciences has developed advanced material processes to produce high performance composite radomes for missile interceptor applications. These unique and proprietary processes have enabled us to produce radome prototypes thathave inherently low dielectric constants and loss tangents for Ka band applications through 1500¿F, exceed the structural requirements and hav ...

"It is proposed to develop a novel growth system capable of producing large diameter and long Semi-Insulating SiC crystals. The proposed system aims to achieve semi-insulating properties in the crystal by reducing the impurity levels in the reactorassociated with the graphite containment elements. The proposed growth system is based on using gas precursors instead of SiC powder, and uses a nove ...

"The terahertz (THz) wave region is an underutilized electromagnetic spectrum in which generation is difficult. The existing THz sources are generated either by large and expensive free electron laser or by pulsed optical radiations. There is an increasedneed for continuous THz wave source of high temporal and spatial coherence. The practical use of THz spectrum requires new laser technology th ...

"This SBIR Phase I proposal addresses a need for improved UV and deep UV filters for aerospace and defense applications. A new approach to the design and fabrication short pass filters, based on a new photonic material, will allow filters to be made withtransmission at wavelengths as short as 130nm or less. Both these properties are unachievable by any other means. In Phase I, it is proposed to ...

"This proposal considers the potential of direct casting of micro channel cryocooler regenerators. Currently, cryocoolers use regenereators made of packed spheres, which decrease the efficiency of the regenerator and, of course, the cryocooler itself.This is an important issue when considering placing cryocoolers on satellites and the cryocooler itself utilized almost half of the power supply. T ...

"High performance fiberoptic switches are in great demand for use in both modern commercial and defense communication networks and next-generation military sensing systems. Current fiberoptic switches lack reliability and operation speed. Carrie-classreliable switch matrix has not been realized because of the intrinsic limitation of existing technologies. Agiltron Corporation proposes to develo ...

"Current host-based intrusion detection systems are mostly based on attack signatures and are unreliable for detecting insider and/or new attacks and they create too many false positives so that administrators become complacent about potential securityrisks. The opportunity exists to build hierarchical statistical models for host-based intrusion detection systems that will perform deviation detect ...
