Shapes & Styles of DiffusersPlanar Surfaces - Amplitude GratingsThese 1D and 2D surfaces consist of patches of absorptive (drilledareas) and reflective areas in an optimal binary sequence whichoffers a combination of absorptive and diffusive properties.
Shapes & Styles of DiffusersRectilinear SurfacesRPGs - these 1D and 2D surfaces can be either based onmathematical number theory or boundary elementoptimization and scatter high frequency sound uniformly.
