Radio-Frequency Actuated Polymer-Based Phononic Meta-Materials for Control of Ultrasonic Waves
Description:
This article describes the achievement of radio-frequency control of a n ultrasonic phononic crystal by encapsulating it in a composite of high k-10% KF-doped BaTiO₃ dielectric nanoparticles with poly(N-isopropylacrylamide) (PNIP Am)-based hydrogel.
