This Small Business Technology Transfer Research phase I program will develop a new class of uncooled THz detectors for the 1-10THz band with a novel design using surface plasmon resonant cavities with integrated metal-insulator-metal tunneling diodes as the detecting element. Tunneling diodes provide ultrafast broadband response, potentially into the visible (300THz), but demonstrated performanc ...

Intuitive mission displays and planning capabilities are needed to enhance pilot and operator situation awareness when teaming with next-generation autonomous vehicles in tactical operations. To address this, we will design and demonstrate Tactical Interfaces for Teaming with Autonomy (TITAN) to increase the shared awareness for manned/unmanned teams in distributed and complex communications envir ...

High G Aerodynamic Controls | Approved for Public Release 18-MDA-9707 (3 Jul 18)

Vertically-aligned carbon nanotubes (VACNTs) will be selectively applied at interfaces in laminated composite structures to effect locally the mechanical properties that limit rotorcraft structures, such as fatigue and damage tolerance. In Phase I this work will quantify these effects in CFRP and CFRP/GFRP hybrid coupons. The VACNT material will be transferred directly onto prepreg plies, but also ...

Recent advances in THz-source stability, power and practicality have opened the door for active THz imaging in both commercial and military settings. AEgis is teaming with U Buffalo to develop a THz detection device that utilizes classical rectification effects in semiconductor point contacts (SPCs) to achieve response in the 1 to 10 THz range and is capable of operating at temperatures over 150 K ...

Quantitative predictions of reactive flow dynamics from large-scale simulations of Liquid Rocket Engines (LRE) appear to be model dependent. Relationships and coupling among the dominant mechanisms most responsible for destabilization are obscured by the complexities of the model and subtle consequences of inherent ad hoc approximations not supported by mathematical rationale. The reliability of ...

The ever-decreasing size of the electronic microchips and the ever-increasing density of electronic components required to support future Air Force platforms are creating the problem of substantial localized heat generation that can impair component operation. State of the art thermal interface materials (TIMs), that are used to dissipate heat from the source to the spreader in a microchip, are se ...

The effective de novo prediction of linear and nonlinear optical properties of materials would be a great resource for developers of military and commercial optical devices. Of particular military interest are multiphoton processes that can be optimized for laser protection as well as for improving photovoltaic efficiencies above the Shockley–Queisser limit, for photodynamic therapy and for opti ...

Metamaterials and photonic crystals are engineered composites that exhibit novel and interesting properties not found using ordinary materials. They have been shown to allow extraordinary control over the electromagnetic field, including molding the flow of energy, amplitude profile of the field, phase of the waves, intermodal coupling, and more. To achieve such control, a set of tools and procedu ...

In this project, we propose to use the radiation-assisted poling technique to enhance the electro-optic coefficient of a polymer that we will integrate within a silicon nano-slot waveguide. The electro-optic coefficient in the slot is expected to improve to nearly its optimal value that it exhibits in bulk material. To avoid a free carrier transit time limit and reduce the radio-frequency propag ...
