Analytical TM scattering from semi-elliptic channel loaded with confocal elliptic cylindrical impedance core is investigated. Fields in every regions are expressed appropriately in terms of Mathieu functions. Applying boundary conditions at the impedance core and across different regions of channels and using orthogonality of angular Mathieu functions result in two simultaneous set of equations which would be solved numerically.
