Broadband pentamode acoustic cloak using single phase solid
Abstract eng: Pentamode acoustic cloak using single phase solid is designed with detailed microstructure. Resonance scattering induced by shear standing wave in the cloak, due to imperfection of practically designed pentamode unit cells, is found to damage the expected broadband property. By increasing perfection level, the resonance frequency is found to shift toward zero with narrowed bandwidth, which can be suppressed by introducing damping effect.
