Silicon carbide is a semiconductor ideally suited for high power, frequency, speed and temperature applications. This project proposes a unique ion beam synthesis method of epitaxial silicon carbide on compliant substrates. The technique produces low energy, high current ions to promote surface mobility for high quality epitaxy. This ion synthesis method bypasses the usual thermal p ...

Compact, low-cost, low-phase noise oscillators play an important role in C3 applications; such as satellite communications, intelligent vehicle highway systems (IVHS), data links for robotics control and wideband local area networks. Commonly, dielectric resonator oscillators (DROs) are used in these applications at microwave frequencies. At millmeterwave frequencies, the DRO is no l ...

Globally, over four billion gallons of spent lubricants are generated annually. Although spent lubricants can be considered a valuable renewable resource, less than 10% of the worldwide supply is actually re-refined into high quality lubricant basestocks. The remainder is typically burned as fuel or disposed of using even less environmentally friendly methods. Although stricter envi ...

A STUDY IS PROPOSED TO DEFINE AND EVALUATE CANDIDATE DUAL BALLISTIC COEFFICIENT (BETA) CONFIGURATIONS WHICH ARE FEASIBLE AND APPROPRIATE FOR THE HOMING PRECURSOR JAMMER (HPJ) SYSTEM. EMPHASIS WILL BE PLACED ON EVOLVING CONFIGURATIONS FEATURING MODERATE-TO-HIGH BETA AERODYNAMICALLY STABLE FIRST-STAGE FLIGHT PERFORMANCE AT HYPERSONIC/ SUPERSONIC SPEEDS, AND LOW-BETA AERODYNAMICALLY STABLE SECOND-STA ...

A STUDY IS PROPOSED TO DEFINE AND EVALUATE FEASIBLE JAMMER EXPULSION CONCEPTS FOR THE HOMING PRECURSOR JAMMER (HPJ) SYSTEM, AND TO ASSESS THE IMPLICATIONS OF CANDIDATE EXPULSION CONCEPTS ON JAMMER AEROTHERMODYNAMIC PERFORMANCE AND REQUIREMENTS. CONCEPTS WHICH FEATURE THE SEQUENTIAL EXPULSION/EJECTION OF INDIVIDUAL JAMMERS AXIALLY OUT THE REAR OF THE CARRIER VEHICLE WILL BE EMPHASIZED. RELIABLE CON ...
