Evanescent Acoustic Wave Scattering by Targets and Diffraction by Ripples Graduate Traineeship Award in Ocean Acoustics
Abstract
This grant was a "Graduate Trainee ship Award" in Ocean Acoustics for the support of Curtis F. Osterhoudt. The purpose of his research was to improve the understanding of the way that acoustic evanescent waves interact with targets buried in sediments in situations encountered in underwater acoustics. A method was developed and tested for the stable laboratory production of acoustic evanescent waves in water based on the reflection of a beam of sound at an interface between the water and an adjacent liquid. Responses of targets illuminated by this evanescent wave field were measured and the major features were modeled. The emphasis was on backscattering from cylindrical targets having strong resonances. The research is discussed in detail in Osterhoudt's Ph. D. Thesis completed at Washington State University in April 2007. The title of the thesis is: "Evanescent acoustic waves: production and scattering by resonant targets."
