...Hasan B. Al Ba’ba’a; Mostafa Nouh Bandgaps, or frequency ranges of forbidden wave propagation, are a hallmark of phononic crystals (PnCs). Unlike their lattice counterparts, PnCs taking the form of continuous structures exhibit an infinite number of bandgaps of varying location, bandwidth...

...Feng-Lian Li; Yue-Sheng Wang; Chuanzeng Zhang; Gui-Lan Yu In the present paper, the Dirichlet-to-Neumann map method is employed to compute the band structures of two-dimensional phononic crystals with smoothly sliding connection conditions between the matrix and the scatterers, which...

.... The analysis presented can be extended to multi-dimensional phononic crystals and acoustic metamaterials. Our findings can be used to guide the design of periodic beam structures in a range of applications ranging from aerospace load-bearing structures to MEMS components used for frequency sensing...
