Hello!

I currently work on the resolution of the Helmholtz equation in 2
dimensions in inhomogeneous medium.
The propagation medium is large and we seek to apply the so-called
spectral methods to solve the 2D Helmholtz equation with a reasonnable
amount of computer memory.

My problem is that I do not know how to deal with the huge convolution
matrix I encounter once I compute the FFT. Does anyone know about these
spectral methods? Or know about a book or an article, a thesis which
deals with it?

Sincerely

Alexandre Piot
