Compact acoustic rainbow trapping in a bioinspired spiral array of graded locally resonant metamaterials
Acoustic rainbow trappers, based on frequency selective structures with graded geometries and/or properties, can filter mechanical waves spectrally and spatially to reduce noise and interference in receivers. These structures are especially useful as passive, always-on sensors in applications such a...
