Resonant mechanical meta-interface suppressing transmission of acoustic waves without mode conversion

Abstract : Physical principles for the creation of meta-interfaces between two elastic media supporting transmission of only mode-converted acoustic waves by use of arrays of resonant mechanical elements that transfer shear and compression/dilatation forces are revealed. Analytical modelling of mechanical structural vibrations according to a lumped-element approximation for mechanical elements oriented obliquely to the interface shows that such meta-interfaces can be applied to the directional transmission of the acoustic waves between solids and liquids. Applications include the acoustic isolation of solid objects in a liquid environment and the reduction of the detection efficiency of solid-object vibrations.
