Radio-frequency (RF) control of an ultrasonic phononic crystal was achieved by encapsulating it in a composite of high k-10% KF-doped BaTiO 3 dielectric nanoparticles with poly(N-isopropylacrylamide) ...

Radio Frequency (RF) engineering forms the backbone of modern wireless communications, radar, satellite systems, and sensor networks by harnessing and manipulating electromagnetic energy across a ...
