Multimodal Local Resonators for Low-Frequency Amelioration of Acoustic Black Holes

Multimodal Local Resonators for Low-Frequency Amelioration of Acoustic Black Holes

Acoustic black holes (ABHs) are effective at suppressing vibrations at high frequencies, but their performance at low frequencies is limited. This paper aims to improve the low-frequency performance of ABH plates through the design of a metamaterial acoustic black hole (MMABH) plate. The MMABH plate...
