Nonlinear geometrical acoustics
Abstract
The paper traces the development of the theory of nonlinear acoustic propagation in bounded and semiinfinite dissipative media from its origins in the theories of linear geometrical acoustics, simple waves, and acceleration fronts. The first part of the paper is devoted to cases when only one component wave is excited, and describes the effects of three types of dissipative mechanisms on unidirectional waves. The second part considers nonlinear waves in finite media where more than one component wave is excited, and describes the interaction and distortion of coupled components.
