This work presents a novel strategy of broadband vibration attenuation using a graded piezoelectric metamaterial beam. A series of electrode pairs with varying lengths are applied to the fully covered piezoelectric beam, and each electrode pair is connected to an identical shunt resonant circuit. Un...
