Deep-subwavelength and hydrostatic-pressure-resistant meta-absorber for broadband low-frequency underwater sound

By embedding center-supported graded-circular-plates (CS-GCPs) into an elastomer, a deep-subwavelength and hydrostatic-pressure-resistant meta-absorber was designed and manufactured for sound absorption (SA) under hydrostatic pressure. The meta-absorber exhibits excellent SAs (>0.842, 0.927 on avera...
