An introduction to the study of the behavior of the acoustic wave propagation in a homogeneous dispersive medium is presented in this work. We consider the stationary problem for a two-fluid channel waveguide. The classical normal mode theory as a solution of the scalar wave equation for an idealized stratified fluid layer lying on a semi-half space is described. Graphical solution of the stationary...
The underwater acoustic wave propagation in the stratified ocean produced by moving airborne sources is investigated. We construct the asymptotics of the acoustic pressure in the ocean on large horizontal distances between a moving in the air source and a receiver located in the ocean. Our study is based on the representation of the acoustic field P(t, x, z) generated by a moving airborne source of...
The spectral parameter power series method is applied to problems of underwater sound propagation in the stratified ocean. This method is based on representations of solutions of vertical Sturm–Liouville problems of the form of power series with respect to the spectral parameter, and it gives an effective dispersion equation for wave numbers and explicit expressions for the propagating modes.
