Some articles on spheroidal, oblate spheroidal:

Spheroidal Wave Function
... Spheroidal wave functions are solutions of the Helmholtz equation that are found by writing the equation in spheroidal coordinates and applying the technique of separation of variables, just like the use of ... They are called oblate spheroidal wave functions if oblate spheroidal coordinates are used and prolate spheroidal wave functions if prolate ... If instead of the Helmholtz equation, the Laplace equation is solved in spheroidal coordinates using the method of separation of variables, the spheroidal wave functions reduce to the spheroidal harmonics ...
Oblate Spheroidal Coordinates - Definition (σ, τ, φ) - Scale Factors
... The scale factors for the alternative oblate spheroidal coordinates are whereas the azimuthal scale factor is ... equation may be solved by the method of separation of variables to yield solutions in the form of oblate spheroidal harmonics, which are convenient to use when boundary conditions are defined on a ...
