In this STTR program, Structured Materials Industries, Inc. (SMI) and partners are developing high efficiency, switchable RF filters. The technical approach is based on thin films of paraelectric BaxSr1-xTiO3 and SrTiO3, which can show piezoelectric behavior under an applied DC bias. When integrated into resonator structures, these materials can act as both an RF filter and an RF switch. Combin ...

Recent times have witnessed enormous advances in high fidelity modeling of electromagnetic (EM) phenomena in the time-domain. To make such simulations tractable, the computational region must be truncated in a manner allowing outgoing waves to leave with minimal reflection from the boundary. HyPerComp Inc., in collaboration with Prof. Thomas Hagstrom of the Southern Methodist University (Dallas, T ...

This program creates a new class of advanced transceiver techology. This technology can create 40 Gbps VCSEL-based micro-transceiver (uTRX) components that operate reliably over the standard military temperature range of -55°C to 125°C in Army environments. uTRXs are low-cost, compact components that can be assembled onto the PCB in close proximity to high-performance ASICs using conventional ...

A technique that enables new methods of obscurant modeling with faster rendering while maintaining or improving physical fidelity is proposed. The proposed technique not only exhibits the statistics of voxel based obscurants, but matches real-world data as well. The main objective from Phase II efforts will be a further refinement of the flow field and particle technique of generating physically c ...

We propose to build an emitter localization and detection system that can geolocate signals in the 800-2400 MHz range. The system can be rapidly-deployed, provide accurate emitter locations, deals with many-emitter problem explicitly, and can find low-power emitters.

The expected life of satellite Li-Ion batteries is determined by many factors, including thermal considerations, electrode chemistries, orbit and mission life, DOD, and pulse power requirements. First-principles battery model literature pertains primarily to orbital cycling at moderate DOD under isothermal conditions without variable power loads. Knowledge must be extended to encompass wider life ...

ABSTRACT: Toyon Research Corporation and the University of California, Santa Barbara (UCSB) are proposing development and feasibility demonstration of advanced algorithms for the detection of vibration signatures in scattered light. The algorithms are being developed for applications including space-based electro-optical (EO)/infrared (IR) sensing at high frame rates and extremely low signal-to-n ...

Mathematical models of physical and biological systems contain parameters that need to be estimated from measured data. Models with parameters distributed probabilistically require the estimates of a probability measure over the set of admissible parameters. We propose to use frequentist-based approaches for non-parametrically estimating probability measures that describe the distribution of par ...

ABSTRACT: The U.S. Air Force has a need to develop a new class of advanced, wide field of view (WFOV) imaging sensors that sample the radiation field in multiple modes: spectral, temporal, polarization, and detailed object shape. These multimodal sensors are to be deployed on high altitude drones to enhance their intelligence, surveillance, and reconnaissance (ISR) capabilities. Smaller versio ...

Approximately 5-6% of military injuries involve some form of major peripheral nerve injury with little chance of spontaneous healing. Currently these injuries lead to major impairment of voluntary muscle function in the limbs and extremities, making tasks of walking, reaching, grasping, etc. very difficult or impossible for many patients. It is not enough to focus therapeutic treatment on the se ...
