Beam paths of flexural Lamb waves at high frequency in the first band within phononic crystal-based acoustic lenses
This work deals with an analytical and numerical study of the focusing of the lowest order anti-symmetric Lamb wave in gradient index phononic crystals. Computing the ray trajectories of the elastic beam allowed us to analyze the lateral dimensions and shape of the focus, either in the...
