  • Atomic Vapor Meets Radio Waves: The Future of Antennas?

    From Fred Bloggs@21:1/5 to All on Fri Oct 20 07:33:56 2023
    'Physicists have developed a new type of radio wave antenna using a glass bulb filled with atomic vapor. The team demonstrated that these atomic radio frequency sensors, utilizing a Rydberg state, are more sensitive and versatile than current antenna
    technologies. Their compactness and broad frequency coverage make them ideal for defense, communication, and satellite technology.'

    Thanks, interesting.
    Not sure about applications...

    Here is a bit more technical info. It strikes me as a technology that
    might require a rather fancy optical bench setup!
