Lamb wave band gaps in one-dimensional radial phononic crystal plates with periodic double-sided corrugations

In this paper, we present the theoretical investigation of Lamb wave propagation in one-dimensional radial phononic crystal (RPC) plates with periodic double-sided corrugations. The dispersion relations, the power transmission spectra, and the displacement fields of the eigenmodes are studied by usi...
