Spheroidal harmonics

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 spherical coordinates lead to spherical harmonics. They are called oblate spheroidal wave functions if oblate spheroidal coordinates are used and prolate spheroidal wave functions if prolate spheroidal coordinates are used. If instead of the Helmholtz equation, the Laplace equation is … WebNov 1, 2012 · The spherical harmonics have the advantage that the different basis harmonic functions are orthogonal over the sphere, making the determination of the associated numerical coefficients easier in theoretical problems.
