Electronically dimmable materials with sufficiently strong visible transmission shift, color neutrality, durability and switching speeds have eluded development since the search began nearly half a century ago. We demonstrate the potential for dynamic optical dimming using plasmonic nanostructures with electrodynamic simulations of promising plasmonic metamaterial architectures. In order to achiev ...

This proposal will outline a bi-directional software defined Free Space Optics (FSO) laser communications testbed with flexible optical elements and reprogrammable waveform and signal processing elements. Vulcan Wireless Inc. currently manufacturers a 1550nm, eye safe, software defined Laser Communications Testbed MD-LC-1 and will use this as a basis for the Phase 1 effort. We will also be teaming ...

Faraday and Utah State University propose to demonstrate the feasibility of utilizing electrophoretic deposition to develop graphene features with controlled functional properties in order to address the DoD need for a spacecraft charging mitigation. Implementation of such materials in DoD mission areas is anticipated to lower costs, improve sustainability, and increase readiness. The proposed Pha ...

The project will develop and validate a geometry scalable CNTFET compact model for HF circuit design and extract the model parameters from the measured characteristics of the fabricated devices. The ballistic and quasi-ballistic transport, quantum and parasitic effects will be accounted for the predicted performance will be compared to 130 nm RF Si-CMOS to determine the conditions for breaking eve ...

Through the proposed Phase I Air Force STTR program, NanoSonic and Virginia Tech will demonstrate metal organic framework materials and electrospray fabrication methods for the manufacture of eye protection devices that are capable of controlling the amount of light transmitted through the device. The objective of this program is to 1) increase the dynamic range and speed of electronically switche ...

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 ...

Echo Ridge proposes to prototype and demonstrate an architecture and key algorithms to support spectrum sharing for Position, Navigation, and Timing (PNT) that focuses on spectrally congested and high likelihood operational scenarios. Four key results are proposed to be delivered: 1) end-to-end Hardware-in-the-Loop (HiTL) lab demonstration of all segments of the solution in Air Force-relevant oper ...

We will develop hybrid wave propagation approach that implements FFT and EMA (Efficient Matrix Algorithms) propagators in a fashion that is transparent to the user but insures the highest efficiency and accuracy for a given propagation problem. We will develop rules to decide which propagation approach is ideal for a given situation. The propagation algorithms will be coded in Vulkan/CUDA and C++ ...

Scramjet engines are designed to operate across a wide Mach number range and typically incorporate isolator sections to provide sufficient back-pressure margin and prevent unstart. As military requirements become increasingly demanding, an active, closed-loop control system is necessary to maintain engine stability and power output. During Phase I, key components of a scramjet control system were ...

Liquid Crystal Arrayed Microcavities (LCAM) are a new hyperspectral technology initiated by collaboration among Spectral Molecular Imaging, Advanced Microcavity Sensors and Montana State University Spectrum Laboratory.At the core of this revolutionary technology lie picoliter volume optical cavities that exploit liquid crystal birefringence for tuning an effective cavity length.During a Phase I on ...
