A Spectral Split-Step Padé Method for Guided Wave Propagation
Daniel Walsken, Pavel Petrov, Matthias Ehrhardt
In this study, a Fourier-based, split-step Padé (SSP) method for solving the parabolic wave equation with applications in guided wave propagation in ocean acoustics is presented. T…
Full reconstruction of acoustic wavefields by means of pointwise measurements
Denis V. Makarov, Pavel S. Petrov
Sound propagation in the ocean is considered. We demonstrate a novel algorithm for full wavefield reconstruction using pointwise measurements by means of a vertical array. The algo…
Study of wave chaos in a randomly-inhomogeneous oceanic acoustic waveguide: spectral analysis of the finite-range evolution operator
D. V. Makarov, L. E. Kon'kov, M. Yu. Uleysky +1
The proplem of sound propagation in an oceanic waveguide is considered. Scattering on random inhomogeneity of the waveguide leads to wave chaos. Chaos reveals itself in spectral pr…
A nonstationary form of the range refraction parabolic equation and its application as an artificial boundary condition for the wave equation in a waveguide
P. S. Petrov, M. Yu. Trofimov
The time-dependent form of Tappert's range refraction parabolic equation is derived using Daletskiy-Krein formula form noncommutative analysis and proposed as an artificial boundar…
