Get this from a library! Nonlinear acoustic wave propagation in atmosphere. [S I Hariharan; Institute for Computer Applications in Science and Engineering.]. We then study linear wave propagation in a coated elastic half-space and show how the dispersion relation can be expressed elegantly in terms of the surface-impedance matrices associated with the layer and half-space. We derive a two-term expression for the wave speed in the long-wavelength limit.

Nonlinear Propagation. When acoustic waves propagate to a far away observer or are initially large enough in amplitude they contain nonlinear effects. Alternatively, propagation of shock waves or sonic booms, through the atmosphere of Earth or another planet, require special mathematics and computational algorithms. Waveguide Propagation of Nonlinear Waves: Impact of Inhomogeneity and Accompanying Effects 1st ed. - Sergey Leble - ISBN: This book addresses the peculiarities of nonlinear wave propagation in waveguides and explains how the stratification depends on the waveguide and confinement. An example of this is an optical fibre that does not allow light to pass through a density .

For adequate modeling of a long‐range sound propagation through atmosphere one needs to know a power spectrum of the temperature and wind fluctuations induced by acoustic. The viscous effect, nonlinear effect, heatconduction effect and relaxation effect can be neglected under these assumptions. the medium is ideal fluid. acoustic waves is much smaller disturbance then background medium. frequency of the acoustic wave is large enough that the propagation of the sound can be regard as an adiabatic process.

Abstract: A non-linear acoustic wave propagation model has been developed to determine the effects of ocean variations in the acoustic field, and to determine the signal measured by a receiver at any distance from an omni-directional source.

Large amplitudes require using full systems of governing equations of fluid dynamics (for sound waves in liquids and gases) and elasticity (for sound waves in solids). These equations are generally nonlinear, and their traditional linearization is no longer possible.
