    Summary:
    New phased-array transmitter design overcomes common problems of CMOS technology in the 300 GHz band.
    Thanks to its remarkable area efficiency, low power consumption, and high data rate, the proposed transmitter could pave the way to many technological applications in the 300 GHz band, including body and cell monitoring, radar, 6G wireless communications,
    and terahertz sensors.

    Are they not already using such frequencies in combo with VNAs to test
    for explosive substances at airports? Like if someone tries to board
    an aircraft with a bottle of 'something' in their hand luggage which
    could represent a security threat, but they need to determine if it is
    within seconds rather than hours?

    What's interesting about the report is that they are claiming to have
    developed a new source of terahertz radiation, in addition to the ones
    we know about and use, some of which are decidedly exotic

    https://en.wikipedia.org/wiki/Terahertz_radiation

    Josephson junctions in high temperature superconductors strike me as
    pretty exotic.

    Possible, but smaller is better?
