Target tracking and aimpoint maintenance are critical functions within a laser directed energy system. Traditionally, the optical sensor is a conventional camera viewing an actively illuminated target. In the absence of turbulence, it is still difficult to point the laser weapon to a specific hit spot when there are no features in the required direction. Further, atmospheric turbulence scintillate ...

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++ ...

The main objective of the proposed Phase II project is to leverage the technology of THz generation in resonantly-pumped quasi-phase-matched (QPM) GaAs structures, jointly developed by Stanford University and Microtech Instruments, Inc., and create a compact and power-efficient commercial THz source with a mW-level average power. This source will be continuously or step-tunable in the 0.5-3 THz ra ...

Radiative heat transfer is a dominant mode of heat transfer in combustion and propulsion systems as well as for hypersonic flow encountered during planetary entry. Solution of the Radiative Transfer Equation (RTE), which is an integro-differential equation, places stringent requirements on the computational resources as: (a) the radiation depends both on spatial and angular dimensions, (b) radiati ...

Accurate and timely surveillance of objects in the near-Earth space environment is becoming increasingly critical to US national security. One of the main difficulties in this domain is efficiently and accurately modeling trajectories of the vast number of objects in orbit around the Earth. The orbital trajectory of a single object is typically modeled as a second-order system of equations which ...

ABSTRACT: During Phase I, PaneraTech in partnership with UCLA-TANMS (NSF Center for Translational Applications of Nanoscale Multiferroic Systems) achieved a groundbreaking success by designing a multiferroic small antenna based on continuous spin rotation in ferromagnetic nanoelements in periodic electrode array patterns. Specifically, we developed Finite Elements Method (FEM) models to design nan ...

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 ...

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 ...

ABSTRACT: Echo Ridge proposes to develop and deliver a suite of prototype EW training tools to support realistic warfighter training in the congested and contested RF environments expected in future operational engagements. The tools consist of an opposing force broadcast capability and an Electromagnetic Spectrum (EMS) monitoring capability which supports both electronic sensing (ES) and electron ...

In the wake of ransomware reaching epidemic proportions and the current anti-ransomware products’ inability to stop its march, there is a great deal of urgency in creating effective countermeasures. Our proposal is to design and subsequently develop a technology called Program Access Control (PAC), that can positively protect data on both consumer and enterprise systems. If successfully dep ...
