TE-wave scattering by a multiangular trough in a conducting plane

Electromagnetic scattering of a transverse electric wave by an infinite loaded trough of a multiangular cross-section is studied using the domain product technique which employs a Mathieu function expansion. The algorithm gives the possibility of a substantial variation of the geometry of the trough without turning to another mathematical model. Numerical examples are presented which demonstrate the validity and capability of the technique.
