domain requires the numerical solution of Laplace's equation, the first step of which is ap- proximating, by interpolation, the curved portions of the filter to a circle in the xy plane.A conformal map is then applied to the filter, transforming the region into a rectangle in the uv plane. A finite difference method is introduced to
