Stealth rubber coating could make submarines nearly invisible to sonar

Pc simulations discovered {that a} materials created from three layers of rubber may soak up most frequencies used for sonar, which if affixed to a submarine would make it tough to detect

A skinny coating of a rubbery materials may make submarines harder to detect with sonar.

Sonar locates submarines by emitting sound at many alternative frequencies. These sound waves replicate off the vessel as an echo which may then be detected by a receiver. However objects coated in supplies that soak up sound are laborious for sonar to identify.

Qingxuan Liang at Xi’an Jiaotong College in China and his colleagues have now designed a brand new coating for masking submarines from sonar that, if absolutely …
