Manipulation of structured electromagnetic (EM) waves is key to boosting wireless communications capacity. Recently, scientists have invented a space-time-coding metasurface that generates structured ...

Modulation is the act of translating some low-frequency or baseband signal (voice, music, and data) to a higher frequency. Why do we modulate signals? There are at least two reasons: to allow the ...

NASA has launched the CANVAS CubeSat to investigate very low frequency (VLF) radio waves from lightning and human activities, tracing their path from Earth's surface into space. This mission bridges ...

A team of physicists has developed a method to detect gravity waves with such low frequencies that they could unlock the secrets behind the early phases of mergers between supermassive black holes, ...

An arbitrary waveform generator (AWG) is a powerful and flexible signal source capable of generating any wave shape within the bandwidth and amplitude range of the generator. Populating an AWG with ...
