SETI's 1977 "Wow!" signal from deep space was even stronger than originally thought, but its source remains a complete ...

RF signals historically are measured using spectrum analyzers, at least that was before oscilloscopes offered sufficient bandwidth for those measurements. With oscilloscope bandwidths over 100 GHz, RF ...

The "Wow!" signal has been etched with a red marker in the memory of advocates for the search for extraterrestrial intelligence (SETI) since its unveiling in 1977. To this day, it remains one of the ...

Radio over fiber transports RF signals via optical fiber, enabling low-loss distribution for wireless networks, radar systems, and radio astronomy applications.

Why electrical circuits operating at optical frequencies is an attractive opportunity. How a new plasmonic arrangement is used to mix electrical signals at optical frequencies. The advantages and ...

Multi-frequency-region parallel sensing (MFRPS) is poised to enable larger-sized, thinner, and more responsive touchscreens.
