The project will remove a key difficulty that currently hampers many existing methods for computing unsteady electromagnetic waves on unbounded regions. Numerical accuracy and/or stability may deteriorate over long times due to the treatment of artificial outer boundaries. We propose to develop a universal algorithm and software that will correct this problem by employing the Huygens' principle an ...

The aim of this STTR program is to develop protocols to discover rare-earth-free/rare-earth-lean magnetic alloys for replacing rare earth (RE) -based alloys for reducing the dependence of supply from China. The development of non-RE high temperature magnetic materials is very challenging. In Phase I, CFDRC in collaboration with its university partner has demonstrated a proof-of-concept computation ...

In this STTR proposal, we propose a novel computational technology for analyzing millimeter wave and sub-millimeter wave scattering from complex and electromagnetically extended objects and environments. The core of our formalism lies in a technique for rapidly calculating and coherently adding fields produced by different scatterer constituents, ranging from conducting, flat surfaces to penetrabl ...

ADA, in collaboration with USC, proposes the development of a high energy hybrid battery/supercapacitor to replace multiple heterogeneous energy storage devices currently used by the Army soldier. The hybrid electrical energy storage system (HEESS) will be developed incorporating ADAs high energy supercapacitor and a commercial-off-the-shelf high energy Li-ion battery through an externally paralle ...

We will design, fabricate, and characterize an ion microtrap equipped with an integrated in-situ cleaning capability and with integrated optical access ports. The trap will be made of optical quality fused silica. The trap design and the fabrication process will allow for future developments, such as the addition of an integrated oven, UHV-maintaining subsystem, and rapid trap exchange with interc ...

Our objective is to significantly increase the electron transfer efficiency of the enzyme-catalyzed reactions at electrodes and thereby establish a new state-of-the-art power source for military and commercial systems. The approach is to develop a novel method for orienting enzymes immobilized onto the electrode surface that results in facilitated charge transfer. The proposed bio-electrode techn ...

Autonomous or teleoperated navigation of unmanned ground vehicles (UGVs) is difficult even in benign environments due to challenges associated with perception, decision making, and human-machine interaction, among others. In environments with rough, sloped, slippery, and/or deformable terrain, the difficulty of the navigation problem increases dramatically. In this effort, Quantum Signal, LLC, Un ...

A novel and new method of measuring the far-field noise of a helicopter is proposed by the Delta Group International/University of Maryland team that uses a hot-air-balloon as the measurement platform. The method meets the Army STTR objectives of being capable of measuring helicopter noise above and near the tip-path-plane of the helicopter without measurable ground reflections. The new method i ...

Approximately 5-6% of military injuries involve some form of major peripheral nerve injury that has 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. Focusing therapeutic treatments to segmental nerve in ...

In this STTR project, EMAG Technologies Inc. and the University of Michigan have joined forces to propose the development of a visual software tool for stochastic analysis of coupled electromagnetic and circuit problems often encountered in EMC/EMI scenarios. The proposed tool will integrate novel and computationally efficient uncertainty quantification (UQ) algorithms with EMAG's commercial EM an ...
