Velocity Reversal

abstract The “shadow” from an Epstein “sech2” profile is caused by exponential decay of amplitude. The decay constant, which is independent of frequency, is identical with that obtained from the classical ray theory. The spectral amplitudes and theoretical seismograms evaluated numerically show the effect of the reversal on the acoustic wave propagation.

Bifurcation And Stability

Abstract The non-linear dynamic behavior of acoustic wave propagation in underwater sound channel is studied by a parabolic ray theory using Munk’s sound speed profile. The Hamiltonian system of the ray trajectory is forced by a single mode sinusoidal internal wave. The amplitude and wave length of this excitation are used in a bifurcation analysis. The regions of instability are located by numerical simulations and visualized through a sequence of phase diagrams and Poincaré maps.
