Teraphysics Corporation has assembled and tested a 0.65 THz backward wave oscillator (BWO) with a helical slow wave circuit. The helix is a coil of gold wire, which is smaller in outside diameter than a human hair. It is supported by a thin diamond sheet and mounted within a micromilled copper block.
