Abstract :
The usefulness of impedance boundary conditions for the investigation of field problems concerning corrugated surfaces is studied by its application to the scattering by a partially corrugated conducting prism. The corrugated portion of the prism is represented by an impedance surface and the behaviour of the surface currents and the scattered fields are examined. The results are also compared with available data on a similar problem.
