The extended Fourier pseudospectral time-domain method for atmospheric sound propagation

The Journal of the Acoustical Society of America, 2010
An extended Fourier pseudospectral time-domain (PSTD) method is presented to model atmospheric sound propagation by solving the linearized Euler equations. In this method, evaluation of spatial derivatives is based on an eigenfunction expansion. Evaluation on a spatial grid requires only two spatial points per wavelength. Time iteration is done using a

The Fourier Pseudospectral Method for Two-Dimensional Vorticity Equations

IMA Journal of Numerical Analysis, 1987
The authors develop a Fourier pseudospectral method for solving two- dimensional vorticity equations. They prove the generalized stability of the numerical scheme and they give convergence estimates which depend on the smoothness of the solution of the vorticity equations. Some numerical results are presented and discussed.

Fourier-matching pseudospectral modal method for diffraction gratings

Journal of the Optical Society of America A, 2011
A Fourier-matching pseudospectral modal method [PSMM(f)] is developed for analyzing lamellar diffraction gratings or grating stacks. A Chebyshev pseudospectral method is first used to accurately calculate the eigenmodes of the grating layers, and then the Fourier coefficients are matched at the interfaces between the layers.

The Fourier pseudospectral method with a restrain operator for the RLW equation

Journal of Computational Physics, 1988
The authors consider the periodic problem of the reduced long wave (RLW) equation. Since the accuracy of numerical solutions of both finite element methods and difference methods is limited even for very smooth solutions of the equation, the authors develop a new Fourier pseudospectral method, modifying filtering techniques of \textit{H.-O. Kreiss} and
