Analytical Study of a Monolayered Vibroacoustic Metamaterial
Majdi O. Gzal, Lawrence A. Bergman, Kathryn H. Matlack +1
This study investigates a vibroacoustic phononic metamaterial system composed of repeated monolayered membrane-air cavity unit-cells to assess its efficacy in controlling sound wav…
