In Modified Wavenumber Approach

Parth1999 · May 5, 2021, 05:45

Hi Guys
I was asking that in modified wavenumber approach we write k = (2*pi)/( $\lambda$ ) and for uniform grid it can be written as (2*pi)/(L/n) but how to write the value of k for non uniform grid or structured non uniform grid(discrete spectral representation of a function on a 1D non-uniform grid).

Please help

Could you better formulate your question? Are you assuming that you want a discrete spectral representation of a function on a 1D non-uniform grid?
