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 ...

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 ...
