Nanohmics proposes to develop a hyperspectral imager for aft-looking sensing of phenomenology associated with target vehicles.The payload is designed to operate with existing components and has no moving parts.The high spectral resolution will provide feedback for signature models and the spatial resolution will allow the spectral signatures to be associated with specific phenomena.Approved for Pu ...

HIGH-DENSITY ENERGY STORAGE AND FAST DISCHARGE WILL BE CRITICAL IN A VARIETY OF HIGH POWER AEROSPACE APPLICATIONS. CAPACITORS ARE IDEAL FOR THESE PURPOSES, AS WELL AS FOR POWER CONDITIONING AND FILTERING. UNFORTUNATELY, BULK POWDER-BASED DIELECTRICS USED IN CAPACITORS HAVE SEVERE LIMITATIONS, ESPECIALLY THE HIGH NUMBER OF SHORT-INDUCING DEFECTS CAUSED BY POOR CONTROL OF MATERIAL PROPERTIES IN CERA ...

The proposed effort focuses on the need for innovative, space realizable, self-contained actuators for precision positioning and vibration isolation. The proposed mechanism is a sealed linear actuator capable of high bandwidth (O-lkHz) control. A design feasibility study will be performed on the use of piezoelectrics in an innovative configuration to provide robust linear actuation for positioning ...

An innovative discharge geometry for a very compact, area cooled, high average power CO2 laser employing a two mirror, waveguide-stable optical cavity is proposed. The specific Phase I result sought is the generation of an average CO2 output power of 1 W/cm2 of wall cooling area in a geometry that has a total cooling area of 140 cm2. A lightweight CO2 amplifier version of a future Phase II devic ...

EXPLOITATION IN MICROELECTRONICS OF THE VERY HIGH DIELECTRIC CONSTANTS OF FERROELECTRIC PEROVSKITES SUCH AS BATIO3 AND PZT HAS BEEN LIMITED BY MATERIALS PROCESSING AND COMPATIABILITY PROBLEMS. HIGH QUALITY FERROELECTRIC THIN FILMS HAVE NOT BEEN GROWN AT TEMPERATURES COMPATIABLE WITH STANDARD SI OR GAAS PROCESSING TECHNOLOGIES. A HUGE PAYOFF AWAITS ONE WHO CAN UNLOCK THE POTENTIAL OF FERROELECTRIC ...

APPLICATIONS OF HIGH-TEMPERATURE SUPERCONDUCTING MATERIALS TO TUNNELING DEVICES HAVE BEEN LIMITED BY FABRICATION PROBLEMS RELATED TO THE INTRINSIC ANISOTROPY OF THESE MATERIALS, TO THEIR EXTREMELY SHORT SUPERCONDUCTING COHERENCE LENGTH, AND TO THE POOR ELECTRICAL PROPERTIES OF THE NATIVE SURFACE OXIDE ON THE YBA2CUO7-X (YBCO) FAMILY OF HTSC MATERIALS. MAGNETIC FLUX-COUPLED SWITCHING DEVICES MAY BE ...

DEPENDING ON THE PARTICULARS OF AN ENGAGEMENT SCENARIO, DOPPLER SHIFTS DUE TO THE RELATIVE MOTION OF A MISSILE AND A SENSOR PLATFORM CAN BE IN EXCESS OF 1000 MHZ FOR A COHERENT COE2 SENSOR SYSTEM. SINCE THE RESPONSE OF THE SENSOR'S HETERODYNE DETECTOR CAN BE DEGRADED BY AS MUCH AS 50% AT THESE LARGE OFFSET FREQUENCIES, A LOCAL OSCILLATOR CAPABLE OF BEING TUNED EITHER UP OR DOWN 1000 MHZ TO COMPENS ...

DIAMOND HAS EXTREMELY HIGH THERMAL CONDUCTIVITY, A LARGE BANDGAP, HIGH CARRIER MOBILITIES AND LOW NEUTRON AND IONIZING RADIATION DISLOCATION CROSS SECTIONS. THESE PHYSICAL PROPERTIES MAKE IT AN IDEAL MATERIAL FROM WHICH TO CONSTRUCT ELECTRONIC DEVICES FOR HIGH TEMPERATURE, HIGH FREQUENCY AND/OR HIGH RADIATION APPLICATIONS. ONE PARTICULARLY IMPORTANT APPLICATION OF DIAMOND LIES IN SUPERLATTICE STRU ...
