Gravitational waves are ripples in spacetime produced by violent cosmic events, such as the merging of black holes. So far, ...

Researchers develop TRFS, a non-invasive radio frequency technique that can suppress or excite deep-brain activity to treat depression, epilepsy, and Parkinson’s.

A new study found that precise application of radio waves can change the activity of brain cells in ways that could counter neurological conditions.

Pinpointing the minimum and maximum transient noise bandwidth for a transient noise simulation is a non-trivial task. But these algorithms can help ease the challenge and ...

Physicists have for the first time observed light drifting sideways in discrete, quantized steps, reproducing a quantum Hall effect that was previously seen only in electrons confined to ultra-thin ...

Optical frequency combs—laser sources that emit evenly spaced colors of light—are foundational, ubiquitous tools for ...

GHz phased array radar system featuring Pulse Linear Frequency Modulated (LFM) modulation and based on an AMD Artix-7 FPGA. Two versions are available: the AERIS-10N (Nexus), providing up to 3km range ...

Measuring high aspect ratio and composite micro-trenches without damage is critical for advanced microfabrication, yet conventional coherence scanning interferometry often suffers from a low signal-to ...

The 1983 US Postal Service first-day cover for the 20-cent Edwin Howard Armstrong commemorative stamp from the American Inventors series, featuring a Colorado Silk cachet illustrating Armstrong at his ...
