Abstract
The elliptic coordinates are used to build a new families of 2D coordinate systems which are orthogonal and admits the separation of variables. The charts of characteristic curves are constructed for these systems and compared with Mathieu's. The possible applications are in quantum mechanics, diffraction theory, vibrations and classical dynamics.
