A Chebyshev Spectral Method for Normal Mode and Parabolic Equation Models in Underwater Acoustics
TL;DR: In this paper, the results of the Chebyshev spectral method and the traditional finite difference method are compared for an ideal fluid waveguide with a constant sound velocity and a deep-sea Munk speed profile.
Application of a Chebyshev Collocation Method to Solve a Parabolic Equation Model of Underwater Acoustic Propagation
TL;DR: In this article, a new discrete parabolic equation (PE) model using the Chebyshev collocation method (CCM) is derived, and the code (CCMPE) is developed.

A Chebyshev-Tau spectral method for solving the parabolic equation model of wide-angle rational approximation in ocean acoustics.
TL;DR: The proposed discrete PE model using the Chebyshev spectral method is suitable to provide high-precision reference standards for the benchmark examples of the PE model and has a longer running time than the finite difference discrete PE program.
