Description
Summary:In this article a sphere is taken to be partially filled with fluid so that its interior is part fluid and part air. A set of basis of functions, based upon an origin at the fluid/air interface, is used for the interior and a set of basis functions based upon the center of the sphere is used for the shell and exterior of the sphere. These sets of basis functions are coupled at the shell/interior interface and the resulting coupled system of equations solved to yield the scattered field. Numerical computations using this approach are presented for varying amounts of fluid-fill and for varying incident plane waves.
