(abstract) Oblique Insonification Ultrasonic NDE of Composite Materials for Space Applications
Mar 17, 1997
Bar-Cohen, Y.; Lih, S. S.; Mal, A. K., 1997, "(abstract) Oblique Insonification Ultrasonic NDE of Composite Materials for Space Applications", https://hdl.handle.net/2014/27659, Houston, TX, JPL Open Repository
In recent years, a great deal of research has been exerted to developing NDE methods for the characterization of the material properties of composites as well as other space structural materials. The need for information about such parameters as the elastic properties, density, a...
1KW power transmission using Wireless Acoustic-Electric Feed-through (WAEF)
Mar 3, 2008
Sherrit, S.; Bao, X.; Badescu, M.; Aldrich, J.; Bar-Cohen, Y.; Biederman, W., 2008, "1KW power transmission using Wireless Acoustic-Electric Feed-through (WAEF)", https://hdl.handle.net/2014/41735, ASCE American Society of Civil Engineers, Earth and Space 2008, Long Beach, California, March 03, 2008., JPL Open Repository
A variety of space applications require the delivery of power into sealed structures. Since the structural integrity can be degraded by holes for cabling we present an alternative method of delivering power and information using stress waves to the internal space of a sealed stru...
