ELECTROMAGNETIC SCATTERING BY A RIGHT ANGLED ANISOTROPIC IMPEDANCE WEDGE

The 3-D electromagnetic scattering of plane waves from a right angled impedance wedge, with one anisotropic face, is addressed. An exact int egral representation for the total field is obtained by resorting to t he Maliuzhinets method. The integral representation for the field is d efined along the Sommerfeld integration path, so that it can be asympt otically evaluated by standard procedures. The particular kind of anis otropic impedance considered for one of the faces of the wedge is suit able for modelling corrugated surfaces or strip loaded grounded dielec tric slabs, with corrugations or strips perpendicular to the edge.
