The acoustic absorption characteristics of anechoic coatings attached to the surface of underwater vehicles are closely related to their acoustic stealth. Owing to the essential property of local resonance, the narrow sound-absorption band cannot mee

The underwater anechoic coating with local resonant units is an effective method to achieve low-frequency sound absorption. However, the structure obtained in this way is not satisfactory in the sound absorption effect of mid-high frequency bands. Ca

Although the conventional locally resonant acoustic metamaterials (LRAMs) have shown better sound absorption performance in the low frequency band, the effective frequency range of the sound absorption performance is quite narrow relatively. To overc
