Toyon is proposing to develop multiplier diode technology with record power handling in the 200 – 400 GHz output frequency range using Gallium Nitride (GaN) materials. This technology is needed to effectively utilize the high pump power now available from mmWave GaN power amplifiers. GaN has inherent material property advantages including high electric field strength, electron velocity, and ther ...

The Tunable Active HEterodyne Terahertz Imager (TAHETI) system will use Terahertz Quantum-Cascade Lasers (QCL) combined with a Schottky diode detector for ultra-high dynamic range heterodyne imaging. Distributed feedback (DFB) QCLs with milliwatt power levels are engineered to emit at slightly offset frequencies, and are used as local oscillator and illumination for imaging. The QCLs will be down ...

For many communication, applications the demand for more bandwidth is a never ending problem. Military system applications often can exceed commercial demands by an order of magnitude or more as SIGINT and IMINT data collection and transmission are keys to our National Security. Optical delivery of RF signals is an increasingly important topic for applications including RF antenna remoting, sign ...

ATA Engineering, Inc. (ATA), partnered with a nonprofit research institution, CUBRC, Inc., (CUBRC), proposes a Phase II STTR project to further develop and continue validating a novel multiphysics simulation technology. The project team will implement the technology in a fluid-structure-material interaction (FSMI) software toolset that incorporates mutual interactions between aerodynamics and stru ...

Structural Health Monitoring (SHM) can be reliably used to perform on-line health monitoring of any type of structures with minimal human involvement. Current SHM systems can perform the functions required but are heavy, bulky and difficult to integrate with the structure to provide on-board real-time structural integrity assessment. Embedding of currently available sensors and electronics used by ...

In Naval, surface electronic warfare (EW), visual displays form critical bridges between warfighters and the complex operational radio-frequency (RF) spectrum they must monitor and interpret. Surface electronic warfare operators and supervisors must monitor and interact with multiple, stove-piped display systems in order to perform their work. Further, the visual displays they employ are not desig ...

During Phase II of the proposed program, Science and Technology Applications, LLC (STA), proposes to find a green replacement for ammonium perchlorate (AP). During Phase I of this program, the novel tetranitroborate, B(NO2)4-, anion, was identified as a potential high-oxygen carrier. Its combination with the NH4+ cation would result in the formation of ammonium tetranitroborate (ATNB), NH4+B(NO2)4 ...

The strain engineering effort will constitute development of a synthetic biology toolkit applicable for food waste conversion in clostridium. The engineered strain will enable high efficiency conversion of army food waste to fuel. The proposed project will scale up a clostridium based fermentation method to produce fuel from food waste. A batch reactor will be optimized. Overall techno-economic fe ...

Hypersonic systems travelling above the speed of Mach 5 impart intense thermal stress on the airframe, requiring the use of refractory alloys to withstand the heat. The leading edges of hypersonic airframes and scramjet engine intakes are required to be sharp, smooth, and highly accurate to reduce drag and prevent unwanted shock waves due to manufacturing errors. Additionally, rocket engines, both ...

Scanning probe microscopy (SPM) is a technique used to detect near-field interaction when a sample is rater-scanned by a probe. Example include atomic force microscope (AFM) and scanning tunneling microscope (STM). It offers nanometric and atomic image resolution. In this field, an emerging technique, Near-Field Scanning Microwave Microscopy (SMM), utilizes microwave evanescent waves to attain the ...
