Double-negative flexural acoustic metamaterial

Double-negative flexural acoustic metamaterial

We present an acoustic metamaterial for flexural waves with both negative density and elastic modulus. By means of an analytical lumped-element approach, we introduce a combination of resonant elements on the surface of a plate. Following on from experimental demonstrations and theoretical work, neg...
