Research on Acoustical and Optical Scattering, Optics of Bubbles, Diffraction Catastrophes, Laser Generation of Sound, and Shock Induced Cavitation
Abstract
The research summarized concerns a variety of phenomena associated with the propagation and scattering of acoustical, optical, and shock waves. The topics considered fall under the following four categories: 1) Acoustical scattering theory and experiments (focused backscattering from spheres due to transmitted wave and Rayleigh wave acoustical glories, nearfield effects in acoustic scattering, backscattering from a torus, and distortion of focused pulses); 2) Scattering of light from bubbles in liquids and other problems in electromagnetic scattering of value to acoustics and naval technology (critical- angle scattering of light from bubbles, strong cross-polarization in near- forward and backward scattering from bubbles, optical measurement of the amplitude of radial oscillations of bubbles, an optical retro-reflector for use in water, a novel hyperbolic-umbilic diffraction catastrophe, and radiation torques on spheres); 3) Characterization of sound generated in water by modulated laser beams (production by a pre-existent bubble in water, radiation pressure, and heating in water); and 4) Rapid cavitation induced by the reflection of shock waves.
