Περίληψη:
The elastodynamic response of finite 3D phononic structures is analyzed by means of comparing experimental findings obtained through a laser Doppler vibrometry-based methodology and theoretical computations performed with the layer-multiple-scattering method. The recorded frequency-gap spectrum of the phononic slabs exhibited a good agreement of theory to experiment. Along these lines, a newly developed technique, based on laser Doppler vibrometry, has been proposed and validated for the dispersion efficiency in 3D phononic metamaterials. © 2019 IOP Publishing Ltd.
