Ultrafast laser technology offers compelling capabilities for national defense, state-of-the-art health care, and the materials processing industry. The development of this technology into commercial form factor hardware has been limited mostly by the size, cost, complexity, and/or pulse energy limitations of current ultrafast laser systems. Optical fiber based ultrafast lasers have dramatically d ...

We are proposing to develop a process for large area fabrication of metamaterial films with electromagnetic responses that can be manipulated in the infrared region to enable tailored reflectivity and emissivity. Because the approach is based on metamaterials, this technique can readily be scaled to higher or lower frequencies.

The US Navy needs the capability to model acoustic propagation in complex ocean environments containing natural or man-made objects. Such accurate modeling requires the solution of the wave equation in the ocean containing scatterers. In the absence of the scatterer, the oceanic waveguide can be assumed to be axially symmetric. This allows certain types of physically valid approximations to be mad ...

The rotorcraft aerodynamic interaction is a complicated problem and remains an extremely challenging aspect of rotorcraft analysis. This STTR is dedicated to developing a solution for the complicated rotorcraft aerodynamic interaction problem. The Phase I research coupled a state-of-the-art vortex particle method (VPM) with an unstructured Navier-Stokes CFD body surface solver and prototyped a hyb ...

Transphorm proposes to demonstrate a normally off fast high voltage Gallium Nitride power switch solution. The switch would block to 1200V, have a threshold voltage greater than 5 V, and the phase 2 switch will target an on resistance less than 15 ohm-mm and current more than 1 Amp. To accomplish these targets, Transphorm will combine the design requirements of realizing a high (and positive) thre ...

Information Systems Laboratories (ISL) and Florida Atlantic University (FAU) propose to develop and test a system that uses existing signal processing algorithms coupled with innovative construction technology developed ISL under our E-Field sensor programs and FAU under UUV programs. The Challenge is to develop a small system package with the capability to intercept active threat emissions early ...

The Toyon-MST team proposes to perform research and development of a system which fuses multi-spectral EO and 3D data collected with a low-cost LIDAR to enable improved perception for unmanned ground vehicles (UGVs). The scope of the proposed work includes development of algorithms and software, and development, implementation, integration, testing, and delivery of a prototype, to perform EO-LIDAR ...

In recent years, the need for highly reliable, durable and non-intrusive systems for monitoring the health condition of naval structures becomes more and more recognized. Of particular importance is the condition based maintenance of Navy rotating machinery (motors, generators, pumps, gear systems, etc.). Such Structural Health Monitoring (SHM) systems should be able to detect failures in their ea ...

A high-voltage, high-capacity, inexpensive cathode material for lithium-ion batteries (LIBs) is proposed. The cathode material employs carbon nanotubes and additional nanostructures to support efficient transport of Li ions. The resulting LIBs will support high transient and pulsed loads while offering enhanced safety and lifecycle performance. Proof-of-concept LIB cells were demonstrated in Phase ...
