Abstract:

An incident plane wave is scattered from a periodic corrugated surface consisting of semi-infinite parallel plates, alternately filled with density and wavenumber inhomogeneities, having hard Neumann boundaries. Amplitude coefficients of the fields in the various regions are related via sets of linear equations, the latter of which are solved using the modified residue calculus technique. The two examples treated are zero-thickness plates with arbitrary incident angle and no inhomogeneity, and normal incidence with alternate sets of plates filled with a constant wavenumber and density inhomogeneity. The edge condition is derived for these inhomogeneous regions. Author
