Multiple wide band gaps in a convex-like holey phononic crystal strip
A convex-like one-dimensional holey phononic crystal (PnC) strip with multiple wide band gaps but simple construction is investigated. By dint of the unique folding topology constituted by deformable L-shaped connectors and rigid lumps, the wide band gaps can exist with a compact spatial size. Moreo...

| description | A convex-like one-dimensional holey phononic crystal (PnC) strip with multiple wide band gaps but simple construction is investigated. By dint of the unique folding topology constituted by deformable L-shaped connectors and rigid lumps, the wide band gaps can exist with a compact spatial size. Moreover, the geometrical parameters are tunable in a large range. A maximum band gap of up to 63% is achievable. These salient merits outweigh the already published counterparts, enabling the proposed PnC strip to be a more promising candidate for engineering applications. Therefore, we are convinced that such a folding strategy of unit cells provides a practicable direction for the further structural design of PnC devices. |
