Using high school trigonometry combined with knowledge of four-quadrant multipliers to form a frequency quadrupler.

With a clever design, researchers have solved eddy-current damping in macroscopic levitating systems, paving the way for a ...

Plasma waves can experience sudden changes in frequency with drastic effects, which are important to correctly model.

The world's most sensitive table-top interferometric system—a miniature version of miles-long gravitational-wave detectors ...

As these orbiting black holes emit gravitational waves, their orbits tighten due to the loss of angular momentum from the system ... had detected low-frequency gravitational waves, a historic ...

At European Microwave Week (EuMW) 2025, Keysight Technologies will demonstrate cutting-edge solutions that accelerate radio frequency (RF) and millimeter-wave (mmWave) innovation across space, defense ...

Earth is surrounded by a radio field caused by very low-frequency waves. This field pushes away the Van Allen Belts, a radiation swim-floaty that surrounds Earth's middle. Van Allen radiation hinders ...

Computer Science and Engineering Ph.D. student Nayan Bhatia demonstrates Pulse-Fi, technology that uses WiFi signals to measure a person's heart rate. Heart rate is one of the most basic and important ...

When electrical activity travels across the brain, it moves like ripples on a pond. The motion of these "brain waves," first observed in the 1920s, can now be seen more clearly than ever before thanks ...

As sizzling temperatures sweep across Southern California this week, UCLA researchers have released a new finding that the duration of heat waves is increasing faster than global warming. Researchers ...
