THIS PROJECT FOCUSES ON DESIGNING A STABLE AND ROBUST MICROSENSOR PROBE FOR DIELECTRIC SPECTROSCOPY THAT IS CAPABLE OF OPERATING OVER A WIDE FREQUENCY RANGE, AND ELIMINATES ALL KNOWN PROBLEMS IN THE MEASUREMENT SYSTEMS USED AT VARIOUS LABORATORIES. TO INTERPRET THE DIELECTRIC SPECTRA, DECONVOLUTION METHODS ARE BEING DEVELOPED TO ESTIMATE THE PARTICLE SIZE DISTRIBUTION FUNCTION AND THE SURFACE CHAR ...

PHASE GRATINGS THAT CAN GENERATE ARBITRARY OUTPUT ARE USEFUL FOR BEAM DIAGNOSTICS, MULTICHANNEL IMAGING, OPTICAL COMMUNICATIONS, AND OPTICAL DIGITAL COMPUTING. BY USING DIRECT-WRITE METHODS FOR FABRICATING SURFACE-RELIEF DIFFRACTIVE OPTICS, UNIQUE BEAM SHAPING FUNCTIONS CAN BE IMPLEMENTED THAT WOULD BE EXTREMELY DIFFICULT OR IMPOSSIBLE BY HOLOGRAPHIC METHODS. USING AN ITERATIVE FOURIER-TRANSFORM A ...

THIS RESEARCH FACILITATES THE DEVELOPMENT OF DIODE LASER-BASED INSTRUMENTS THAT PROVIDE EXCEPTIONAL SENSITIVITY AND SELECTIVITY FOR THE REAL-TIME DETECTION OF IMPORTANT GASES IN HARSH, HIGH TEMPERATURE, HIGH PRESSURE ENVIRONMENTS. THESE INSTRUMENTS TARGET THE NEEDS OF COAL-FUELED ENERGY CONVERSION SYSTEMS THAT REQUIRE HOT GAS CLEANUP PROCESSES TO REDUCE EMISSIONS. THIS APPROACH, WHICH MEASURES ABS ...

A SYNTHETIC PROGRAM IS PROPOSED TO ENGINEER POLYMER MATERIALS THAT HAVE A HIGH DIELECTRIC STORAGE DENSITY, LARGE DIELECTRIC CONSTANT, LOW DIELECTRIC DISSIPATION, AND LIGHT WEIGHT FOR PULSE FORMING LINES FOR PULSED POWER APPLICATIONS. THE SYNTHETIC PROGRAM WAS DEVELOPED BY CONSIDERING MATERIAL GUIDELINES WHICH INCLUDE: 1) INTRINSIC DIELECTRIC STRENGTH; 2) DIELECTRIC CONSTANT; 3) LOW DISSIPATION FAC ...

THE DEVELOPMENT AND USE OF NONDESTRUCTIVE, NEUTRON-BASED ANALYTICAL TECHNIQUES FOR MATERIALS CHARACTERIZATION-INCLUDING NEUTRON-SCATTERING APPLICATIONS USING COLD AND THERMAL NEUTRONS-HAVE BEEN HINDERED BY LIMITED ACCESS TO HIGH FLUX SOURCES OF LOW ENERGY NEUTRONS. THIS PROJECT IS DEVELOPING A DEVICE THAT WOULD TRANSMIT A WIDE WAVELENGTH RANGE OF COLD AND THERMAL NEUTRONS THROUGH A SMALL RADIUS OF ...

MANY OF THE ACTIVITIES OF THE HUMAN BODY MANIFEST THEMSELVES BY THE PRESENCE OF A VERY WEAK MAGNETIC FIELD OUTSIDE THE BODY. THIS FIELD IS SO WEAK THAT AN ULTRASENSITIVE MAGNETIC SENSOR IS NEEDED TO ALLOW SPECIFIC BIOMAGNETIC MEASUREMENTS. SUPERCONDUCTING QUANTUM INTERFERENCE DEVICES (SQUIDS) ARE EXTREMELY SENSITIVE DETECTORS OF MAGNETIC FLUX AND HAVE BEEN USED EXTENSIVELY TO DETECT THE HUMAN MAGN ...

THERE IS AN ESTABLISHED NEED FOR A SIMPLE ROBUST TRANSDUCER TO MEASURE PARTICLE VELOCITY IN SEVERE BLAST AND SHOCK ENVIRONMENTS SUCH AS NUCLEAR AND HIGH EXPLOSIVE TESTS. A GAGE CONCEPT IS PROPOSED FOR DEVELOPMENT, BASED ON THE PROVEN MEASUREMENT PRINCIPLES USED IN THE HIGHLY SUCCESSFUL DX GAGE, BUT RECONFIGURED MECHANICALLY AND ELECTRICALLY TO WITHSTAND THE HARSH SHOCK ENVIRONMENTS. THE CONCEPT RE ...
