G. Pelosi et al., HEURISTIC DIFFRACTION COEFFICIENT FOR PLANE-WAVE SCATTERING FROM EDGES IN PERIODIC PLANAR SURFACES, Journal of the Optical Society of America. A, Optics, image science,and vision., 13(8), 1996, pp. 1689-1697
A uniform heuristic high-frequency solution is obtained for plane-wave
scattering from edges in periodic planar surfaces. The case of a wedg
e with periodic impedance boundary conditions on its faces and that of
a truncated strip grating are analyzed. Numerical results are present
ed and compared with reference solutions to validate the heuristic exp
ressions proposed. (C) 1996 Optical Society of America.
