Experimental characterisation of the bound acoustic surface modes supported by honeycomb and hexagonal hole arrays
The Dirac point and associated linear dispersion exhibited in the band structure of bound (non-radiative) acoustic surface modes supported on a honeycomb array of holes is explored. An aluminium plate with a honeycomb lattice of periodic sub-wavelength perforations is characterised by local pressure...
