The suppression of low-frequency torsional vibration has always been a difficult problem in
the field of vibration control. Recently, metamaterials have attracted considerable attention …

This paper reports a novel band structure manipulation mechanism stemmed from taut
strings to shift the Bragg and local resonance band gaps simultaneously. We first developed …

Mechanical metamaterials with low-frequency and broadband bandgaps have great
potential for elastic wave control. Inspired by the ancient window mullions, a novel plate-type …
