Fast Evaluation of the Azimuthal Fourier Modes of the 3D Helmholtz Green's Function and Their Derivatives

Hanwen Zhang

We introduce an $O (M)$ algorithm for evaluating the azimuthal Fourier modes $G_{k, m}$ , $m = 0, 1, ..., M$ , of the three-dimensional Helmholtz Green's function with real wavenumber…

Finding roots of complex analytic functions via generalized colleague matrices

Hanwen Zhang, Vladimir Rokhlin

We present a scheme for finding all roots of an analytic function in a square domain in the complex plane. The scheme can be viewed as a generalization of the classical approach to…
