Physicists are teasing a potential leap in nuclear fusion that sounds almost absurd on its face: a path to reactions that are “billion times” more efficient by swapping today’s ultra-short, ...

CLEVELAND--(BUSINESS WIRE)--Keithley Instruments, Inc., a world leader in advanced electrical test instruments and systems, has introduced a variety of enhancements for its award-winning Model ...

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 ...

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

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 ...

Testing medium-voltage (MV) cables with the high-potential (“hi-pot”) test is typically part of an MV cable testing program. In Parts 4 and 5, we looked at the DC and AC versions of this test. The ...

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 ...
