"Compact Ultra-Wideband (UWB) antennas with broad bandwidth could be of great use in a variety of space-based applications, including radar, communications, and surveillance. The challenge is to deploy a lightweight UWB antenna that is stowable in a smallvolume, that is automatically deployable, and that will be resistant to the harsh space environment. To overcome these challenges we propose an U ...

"This Phase II SBIR research effort addresses several approaches aimed at minimizing lattice constant and thermal expansion mismatches during heteroepitaxial growth of thick (~ several microns) films on Si substrates. A major focus of the research effortwould be one valuation of sub-50-nm linewidth deeply etched one and two dimensional sub-micrometer periodic structures as compliant buffer layers ...

Airborne-based high-energy-laser (HEL) applications are currently receiving serious consideration for both theater defense and tactical systems operations. One of the most critical shortcomings in these undertakings is the ability to sense and correct foraero-optic distrotions to the exiting beam. While these shortcomings in adaptive-optic correction for aero-optical flow transmission are apparent ...

The objective of this proposal is to store large numbers of positrons, also called antielectrons, for long periods of time. Antimatter has the largest specific energy known to humankind, i.e. 180 MJ/microgram. An ordnance package containing micrograms ofpositrons stored for days would comprise an extremely powerful, lethal and revolutionary weapon. We will assemble, test, and operate a positron st ...

The objective of this proposal is to store large numbers of positronium atoms, bound quantum states of electrons and positrons, for long periods of time. Antimatter has the largest specific energy known to humankind, i.e. 180 MJ/microgram. An ordnancepackage containing micrograms of positrons stored for days would comprise an extremely powerful, lethal and revolutionary weapon. We will fabricat ...

The mission of the U.S. Air Force has expanded to include responsibility for global intelligence and force projection-the ability to "reach out and touch someone" anywhere on Earth. To meet these mission requirements, the Air Force has greatly expandedits space technology development efforts.Space-deployable membranes have the potential to yield large gains in systems capabilities through the red ...

A need has long existed for a capability to calculate, simulate and predict the electromagnetic field of an anechoic chamber. This capability is realized in Voss Scientific's BAC-SIM (Benefield Anechoic Chamber Simulation Software), but the ultimate goalof perfect simulation has proved challenging. The biggest obstacle to accurate simulation is the lack of adequate information about the chamber ...

The advancement of shock mitigation technology is critical to the protection of fuzes in future penetrating weapons that are smaller and faster than current weapons. The first objective of this project during Phase II is to continue the research anddevelopment of three shock mitigation approaches, and apply them to develop a mount or housing that protects the most susceptible component of a fuze, ...

For companies engaged in the development of new antenna designs, antenna measurement systems represent a huge initial cost, and a significant barrier to entry into the market. Antenna measurement systems typically use a frequency domain Vector NetworkAnalyzer (VNA) and anechoic chamber or large outdoor range. The cost of such systems starts at around $300,000, which is more than most small compani ...

Under this Phase II SBIR effort Kestrel Corporation proposes to demonstrate the advantages of a distorted grating based wavefront sensor for measuring wavefront aberrations under propagation conditions that simulate the high levels of aberrations found inan Airborne Laser (ABL) application. The proposed technique was conceptually demonstrated during Phase I laboratory experiments where the sensor ...
