In the scalar Helmholtz equation the variables are separated in 11 physically interesting coordinate systems [ 55 ], however for the vector field containing 3 scalar functions, the complete separation of variables is possible only in 6 systems: Cartesian, 3 cylindrical, conical and spherical ones ([ 55 ], Ch.13). Therefore, the formal solution suggested in 1927 by F. Moeglich [ 368 ] for the spheroidal coordinates was practically usefulness until the work of Sh. ...
