Nonlinear transmission lines (NLTLs) have emerged as a pivotal technology in the generation and manipulation of radio frequency (RF) signals. By incorporating nonlinear elements such as varactors and ...
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) ...
A DARPA project could enable radio to be transmitted through water and rock. Radio frequency signals hit veritable and literal walls when they encounter materials like water, soil, and stone, which ...
For the first time in history, a prototype radio has been created that is claimed to be completely digital, generating high-frequency radio waves purely through the use of integrated circuits and a ...
Active sensing encompasses the use of a transmitter and at least one receiver to measure (sense) the transmission or scattering properties of a medium at radio frequencies. In transmission ...
(Nanowerk News) The DGIST Department of Information and Communication Engineering developed a graphene-based high-performance transmission line with an improved operating speed of electrons than using ...
