This battery-powered, 2.4-GHz ISM-band transceiver uses DSSS modulation to achieve a wireless communications range as great as 300 m.

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 ...

An international research team led by Alexander Kuznetsov at the Paul Drude Institute for Solid State Electronics (PDI) in Berlin has demonstrated a fundamentally new way to control the condensation ...

While fewer and fewer people are listening to FM radio today, it was hot stuff amid its widespread rollout during the late 1930s and early 40s. Short for frequency modulation, FM’s appeal compared to ...

John Chowning '66 D.M.A. reflects on his career, his musical journey and the inventions that led to his 2026 win at the ...

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 ...
