    We present a fast Poisson solver on spherical shells. With a special change of variable, the radial part of the Laplacian transforms to a constant coefficient differential operator. As a result, the Fast fourier Transform can be applied to solve the Poisson equation with O(N3log N) operations. Numerical examples have confirmed the accuracy and robustness of the new scheme. © 2011 Global-Science Press.
