Physicists are teasing a potential leap in nuclear fusion that sounds almost absurd on its face: a path to reactions that are ...

Researchers propose a method to detect and map low-frequency excitations in nonlinear materials at nanometer resolution, enabling far-infrared fingerprints.

Sounds that are lower pitched are less studied than other types. Some say it’s a health hazard. Others have doubts. By Lourdes Medrano/Undark Published Apr 17, 2024 8:00 AM EDT This article was ...

Quasiperiodic (QP) very low frequency (VLF) emissions are intermittent bursts of electromagnetic energy, observed in the frequency range of approximately 3–30 kHz, that recur at quasi-regular ...

Wireless transmitters that operate at very or ultra low frequencies (0.3‐30 kHz) typically require some big antenna complexes to handle their communications. Scientists at the Defense Advanced ...

Vibroacoustic Therapy (VAT) is a wellness approach that uses low-frequency sound vibrations and has been studied for its potential effects on relaxation, circulation, and overall physical well-being.

A special technique produces very wide loop BWs in high-frequency PLLs (and hence, indirect (PLL) synthesizers), thereby achieving very low phase noise rivaling that of direct (MMD) synthesizers. A ...
