The research objective is to develop a tunable spatially-varying photonic crystal (SVPC) to achieve the optical propagation properties (reflection and transmission) of the light through the designed structure for the visible and near IR-bands. The light from this SVPC will be able to focus and bend as a function of the spatial variation of the refractive index, input angle, and state of polarizati ...

Nanoparticles represent an attractive alternative in coating processes due to their functional versatility, including surface, optical, conductive and catalytic properties. However, current processes of coating textile products with nanoparticles results in rapid loss of the nanoparticles during laundering or use, leading to a significant decrease in product durability and functionality and increa ...

Navitas will collaborate with the University of Maryland group to develop a flexible microporous Li metal anode. The proposed porous anode will reduce Li dendrite growth via its built-in porosity and increase rate capability via its high surface area. It will enable a conformal, safe, and light weight lithium metal batteries as soldier portable power devices. The Phase I project will demonstrate t ...

ABSTRACT: UltraHiNet, LLC (UHN) proposes to develop a prototype next generation tracking architecture which exploits wide area motion imagery (WAMI) systems and leverages projected heterogeneous high performance computing (HPC) architectures for on-board and ground-based processing of vehicle and dismount targets for urban surveillance. Our research team will focus on the following goals: 1. Dev ...

Metal Additive Manufacturing (AM) research has typically addressed understanding how to maximize performance for an AM material, taking into account microstructural anisotropy, residual stress, defects (such as pores and lack of fusion defects), and surface finish. Optimizing a part then requires significant post processing such as hot isostatic pressing (HIP), heat treatment and surface finishing ...

This proposal is in response to the Defense Health Agency 2017 Phase I SBIR topic 17B-005.The approach is the use of a membrane oxygen pump using newly developed nano-thickness membranes with all the layers less than 1 micron total.Nanometer thickness membranes enable more oxygen output per surface area at temperatures of 300-600 C than current state-of-the -art 600-800 C membranes that are 50-300 ...

Legacy satellite command and control capabilities and their related telemetry operate in a largely stove piped framework. Satellites are still commanded, controlled, and communicated with their ground station in a specific constellation structure. Each ground station is unique to a given constellation and the communications and telemetry are aligned to the specific constellation, underscoring an o ...

NDI of composite Pi/T-Joints presents significant challenges to existing inspection technologies resulting in a barrier to implementation in production. We will investigate feasibility of developing an active thermography NDI solution for real-world inspection of composite structures with T / Pi- joints during the manufacturing process (both green and cured states). Based on the extensive experien ...

In this Phase I effort, HygraTek will explore a novel anti-ice coating formulation to develop icephobic surfaces for naval ship superstructures, decks, equipment and vehicles on board naval ships, e.g. fighter jets, helicopters etc. HygraTek has recently developed a series of different environmentally safe, non-fluorinated, transparent, icephobic coatings. These coatings display the lowest ice-adh ...

Palm-sized unmanned aerial systems (nano UAS) weighing tens of grams have evolved to the point where they are becoming useful to the warfighter. However, their small mass, fragility, and limited batteries still necessitate the use of emerging, low mass/power technologies to meet the full range of potential missions, including new autonomous flight control and collision avoidance strategies, struct ...
