, For the MATLAB code implemented to calculate the dispersion relations of acoustic networks comprising a periodic arrays of narrow air channels
, Note that in the triangular network no band gap opens in correspondence of the even-numbered resonant modes
, as these modes are characterized by identical pressure field phases at the two ends of each individual channel and therefore can be supported by any acoustic network
, The long-wavelength scattering by a junction of N identical channels can be obtained analytically. Interestingly, it does not vanish at a very long wavelength and is strongly anisotropic due to the junction geometry, which makes this scatterer different from an inclusion in a host medium
