(a) Scheme of a QRD Schroeder diffuser composed by N = 7 wells or quarter wavelength resonators. (b) Metadiffuser composed of N = 7 sub-wavelength slits, each of them loaded by M = 3 Helmholtz resonators, with slightly different geometry. (c) Detail of a slit of the metadiffuser showing the geometrical parameters of the cavity of a HR (w c and l c) and its neck (w n and l n).
