Most algorithms for the numerical solution of the two-dimensional variable coefficient Helmholtz equation have running times which scale quadratically with the wavenumber k. I will describe a method which only applies in the case of a radially symmetric potential, but whose running time scales as O(k log(k) ) and which achieves accuracy consistent with the condition number of the operator being inverted.
