Abstract

A uniform heuristic high-frequency solution is obtained for plane-wave scattering from edges in periodic planar surfaces. The case of a wedge with periodic impedance boundary conditions on its faces and that of a truncated strip grating are analyzed. Numerical results are presented and compared with reference solutions to validate the heuristic expressions proposed.
