Ultraviolet Polymerization of Hydrodynamically Shaped Fibers

Materials composed of stacked plates are stronger than the same materials in bulk. However, such stacked plate materials are generally composed of hard, inorganic materials cemented together by a more flexible substance, and do not occur in long fiber shapes. Very few natural or...

Dense Transducer Array

A dense transducer array is an acoustic transducer with relatively high operational bandwidth. It includes a cable harness component that provides and organizes various conductors within piezocomposite substrates to form transducer arrays with minimum impact on electroacoustic performance. Several underwater sonar...
