ELECTROMAGNETIC SCATTERING FROM A CORRUGATED WEDGE

The scattering of a TE-polarized wave from a perfectly conducting wedg e with one of its faces loaded with cavities is considered. The propos ed formulation reduces the analysis of the original problem to two sim pler configurations: one concerning the geometry of the corrugation (i nternal problem) and one concerning the geometry of the perfectly cond ucting wedge (external problem). By resorting to a suitable numerical technique, it is possible to account for arbitrarily shaped corrugatio ns filled with inhomogeneous material. Numerical results demonstrate t he validity of the technique and its applicability to general shape co rrugations. The analysis of corrugated horns is considered and results are shown that demonstrate the flexibility of the procedure to analyz e horns with arbitrarily shaped corrugations.
