The design ofDeployable Reconfigurable Pixelated Antennas (DERPAs) that can operate at different frequencies,with different radiation patterns, and achieve polarization diversity is proposed.The solution proposed, based on optically pixelated silicon or GaAs surfaces, can be used as reflective surfaces for reconfigurable reflect arrays or as reconfigurable active and modular antennas. The optical ...

In this Phase II program, Voxtel will design, manufacture, and benchmark-test additive-manufactured (AM) insulators capable of electrical stress greater than 25 kV/mm, for use in high-electric-field applications, such as high-power microwave (HPM) devices. These insulators will sustain vacuum of 10-7 Torr and withstand 20 psi of pressure. To achieve this goal, Voxtel will synthesize readily additi ...

Some ground crews for aircrafts are exposed to ambient noise levels up to 150 dB SPL: at these levels, conduction of sound through tissues is significant and may be responsible for hearing loss. Protecting the ear canal with earplugs and earmuffs cannotprevent damage caused by tissue-conducted sound. Our research partners at University of Illinois at Urbana-Champaign, experts in bioacoustics and ...

Stellar Science, in collaboration with the University of Maryland, proposes to develop algorithms to demonstrate the feasibility of constructing three-dimensional (3D) models of satellites using ground-based imagery on a standard PC in under 15 minutes. The Phase I effort will address the challenge of registering two-dimensional (2D) images of satellites where traditional feature matchers frequent ...

Crested multi-layer tunnel barriers have been proposed, which offer a revolutionary solution to overcome density to speed trade-offs characteristic of present data storage technologies. Practical implementation of the proposed technology will involve useof thin film materials which are readily manufacturable and CMOS-compatible. A critical need exists for experimental verification of the theoret ...

This Phase II STTR project will continue the research and development of a simultaneous multi-species sensor system for scramjets flight test instrumentation. The sensor system is based on modulation-frequency multiplexing to combine several laser wavelengths and using a single two-color photodiode detector to collect the laser signals along the same optical path. High-sensitivity detection of c ...

In order to measure multi-axis strain fields and strain field gradients interior to composite materials, it is necessary to be able to measure both transverse axes of strain and axial strain. In addition, these sensors should be capable of measuringstrain gradients. Blue Road Research has developed a multi-axis fiber optic grating sensor that can be used to meet these requirements. This proposa ...

This effort joins the MEMS-based deformable mirror technology available from AgilOptics, a New Mexico small business, with the aero-optics technology of the University of Notre Dame to develop an Aero-optics Simulator. This simulator will develop a library of aero-optics patterns to simulate atmospheric distortions for test and evaluation of military or commercial beam control systems.

This contract develops and expands on the technology for micromachining silicon deformable mirrors as a result of work in Stanford research laboratories over the last 5 years. The commerical and military applications of this technology will be exploitedand specific uses will be investigated. Hardware specific to applications will be prepared and evaluated for a few selected uses.The optics indus ...

Future power conditioning, control electronics and directed energy weapons will require significant energy storage for a wide range of power applications. Systems will depend on capacitors to deliver high current and high voltage under repetition. In order to find practical embodiment on mobile platforms, significant advances in compact power sources will be required. In response this need, TP ...
