To address the challenge of suppressing extremely-low frequency vibration and noise in
precision instruments and equipment, a novel non-contact metamaterial beams is proposed …

A multifield continualization technique is introduced that offers a thermodynamically
consistent description of the constitutive and dispersive properties of beam-lattice inertial …

Tunable acoustic metamaterials have excellent sound waves control and manipulation
properties because of their deformations under different stimuli. Pneumatic actuation has …

In this paper, a nonlocal active metamaterial with feedback control is proposed. For a
metamaterial with a symmetric feedback signal, the tunable bandgap and negative effective …
