HIGHLIGHTS
- who: December and colleagues from the Institute of (CAS), China Rowan University, United States have published the article: A review of underwater acoustic metamaterials for underwater acoustic equipment, in the Journal: (JOURNAL)
- what: The experiment shows that the underwater sound absorption performance of the material can be improved by filling the holes with silicone oil, and the sound absorption coefficient is close to one in 750-4000 Hz. How to improve the sound absorption performance while ensuring the pressure resistance of materials is the research focus of SIDM at present.
- future: In this . . .
