We dedicate this paper to the memory of Arnold
Markovich Kosevich. He contributed outstanding work to
many areas of condensed matter theory, and it was a pleasure
to know him. The research of I.S. was supported in part by
the Research Council of Norway (Contract 216699) and the
French National Research Agency (ANR-15-CHIN-0003)

The diffraction of a scalar plane wave from a doubly-periodic surface on which either the Dirichlet or Neumann boundary condition is imposed is studied by means of a rigorous numerical solution of the Rayleigh equation for the amplitudes of the diffracted Bragg beams. From the results of these calculations the diffraction efficiencies of several of the lowest order diffracted beams are calculated as functions of the polar and azimuthal angles of incidence. The angular dependencies of the diffraction efficiencies display features that can be identified as Rayleigh anomalies for both types of surfaces. In the case of a Neumann surface additional features are present that can be attributed to the existence of surface waves on such surfaces. Some of the results obtained through the use of the Rayleigh equation are validated by comparing them with results of a rigorous Green’s function numerical calculation.
