T (terahertz) +‎ ray, modeled after X-ray, coined in Bell Labs in the 1990s.


T-ray (plural T-rays)

  1. (engineering) Electromagnetic waves with frequencies intermediate between, and sharing properties of both, short radio waves and long IR optical waves. This region is defined variously as between 0.1 - 10 THz, 0.3-3 THz or 0.3-30 THz.
    Synonyms: submillimeter wave radiation, terahertz radiation, T-wave
    • 2000 July 2, Robin McKie, “T-rays take over from X-rays”, in The Guardian[1]:
      Military officials believe T-rays could pinpoint the chemical constituents of anti-personnel mines, and spot terrorists carrying explosives into airports. Doctors are interested in T-rays because they are less damaging to living tissue than X-rays.
