A recent theory of Bragg scattering of surface waves by sinusoidal sandbars on a seabed is applied to three cases not examined heretofore: (1) oblique incidence on a strip of infinitely long bars, (2) oblique incidence on the corner of a bar field and (3) seabed with a mean slope. While the Bragg mechanism has been studied previously for sandbars present on many shorelines, it can be a basis for breakwaters where the soil is not strong enough to support a single massive breakwater.
