Standard solvers for the variable coefficient Helmholtz equation in two spatial dimensions have running times which grow at least quadratically with the wavenumber k. Here, we describe a solver which applies only when the scattering potential is radially symmetric but whose running time is O (k log(k)) in typical cases. We also present the results of numerical experiments demonstrating the properties of our solver, the code for which is publicly available.
