Subwavelength acoustic energy harvesting via topological interface states in 1D Helmholtz resonator arrays

We have theoretically and experimentally demonstrated subwavelength acoustic energy harvesting via topological interface states in 1D Helmholtz resonator arrays. The system can produce two types of bandgaps in the subwavelength realm due to the resonance and band folding mechanism, respectively. Thr...
