From: Metamaterials for simultaneous acoustic and elastic bandgaps
The change in the (a) acoustic and (b) elastic bandgaps of the metamaterial at various \(d/C\) and \(L/C\) ratios with illustrations of the cross-sectional view of the single unit cell. The bandgap is represented with a pair of identical lines, with the bottom line denoting the start frequency of the bandgap and the top line denoting the end frequency of the bandgap.
