Superbroad-band actively tunable acoustic metamaterials driven from poly (ethylene terephthalate)/Carbon nanotube nanocomposite membranes
Actively tunable acoustic metamaterials have attracted ever increasing attention. However, their tunable frequency range is quite narrow (tens of Hz) even under ultrahigh applied voltage (about 1,000 V). Here,...
