Problems in Nonlinear Acoustics: Rayleigh Waves, Pulsed Sound Beams, and Waveguides

Abstract

Three project topics, all in the area of nonlinear acoustics, are discussed in this annual summary report: (1) Nonlinear Rayleigh Waves (including diffraction effects in Rayleigh wave beams, local and nonlocal nonlinearity in Rayleigh waves, pulsed nonlinear Rayleigh waves, and nonlinear Stoneley waves); (2) Pulsed Finite Amplitude Sound Beams (including a uniformly valid axial solution for self-demodulation, and measurements of pulsed sound beams in water) ; and (3) Finite Amplitude Sound in Waveguides.
