Abstract: Abstract Locally resonant phononic crystals (LRPCs) have band gaps with low frequencies and the size of the cell is much smaller than the wave lengths of the band gaps. This unique property makes them good… read more here.

Abstract: Abstract First, the dispersion curve of a two-degree-of-freedom locally resonant phononic crystal (LRPC) is calculated by the plane wave expansion method. The result shows that the structure has the characteristics of double bandgaps in the… read more here.
