In the ETH experiment, self-oscillations (blue-red) cause sound waves (green, orange, violet) to travel through the circulator only in one direction. Credit: Xin Zou Researchers at ETH Zurich have ...
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) ...
Additionally, these waves hold great promise for wireless communication. Advances in THz nonlinear optics, which can be used to change the frequency of electromagnetic waves, are essential for the ...
This graphic shows the development of a soliton, which takes about 2.7 nanoseconds. Current begins passing through the center channel causing the magnetization to oscillate. The magnetization under ...
Researchers in Japan and Germany have converted energy from soundwaves into electromagnetic energy, trapping a magnetic "spin current" between metal layers. In the experiment, when sound waves are ...
Salvatore Cezar Pais is a US Navy researcher. Salvatore has three amazing patents that would be incredible breakthroughs in physics if they are true. The least extreme is a patent for Piezoelectricity ...
Michael Hall receives funding from the Australian Research Council and the Foundational Questions Institute. We see them at the beach. They’re behind every sound and light show and the miracle of ...
