Above 275GHz

OFCOM is issuing NoV for bands above 275GHz (the Terahertz bands). Although I have experimented at lightwave frequencies (where the test gear is easy) I have not tried terahertz frequencies. What is needed is very simple design that is "sure fire".  At the moment, I suspect only professionals with access to terahertz test gear will apply.
