Abstract: Abstract In present work, a locally resonant elastic metamaterial (LREM) based on liquid solid interaction (LSI) is proposed, which can attenuate flexural wave in broad low frequency range. By using internal liquid as scattering core… read more here.

Abstract: To date, the vast majority of architected materials have leveraged two physical principles to control wave behavior, namely Bragg interference and local resonances. Here, we describe a third path: structures that accommodate a finite number… read more here.
