Image Theory for Neumann Functions in the Prolate Spheroidal Geometry

Figure 1

A prolate spheroid is centered at the origin, its focal axis is aligned with the -axis, and its interfocal distance is . In terms of the prolate spheroidal coordinates defined in the main text, the prolate spheroid is determined by . A unit source is located at inside the spheroid.
