A wavenumber based extrapolation and interpolation method for use in conjunction with high-order finite difference schemes
In this very consistent paper interpolation and extrapolation errors in large scale computations are analyzed and quantified in the wavenumber space. The authors propose an optimized extrapolation and interpolation method in order to reduce instability. Many numerical examples compare the proposed method results with high-order finite difference scheme results and Lagrange polynomials.
