The propagation of long-wavelength sound in the presence of a metasurface made by arranging acoustic resonators periodically upon or slightly above an impervious substrate is studied. The method of two-scale asymptotic homogenization is used to deriv... Read More about Nonlocal boundary conditions for corrugated acoustic metasurface with strong near field interactions.
