High power transmission experiments with a millimeter wave remote steering launcher, which consists of a square corrugated waveguide and a copper steering mirror at the inlet of the waveguide, were carried out to study the steering capability and the high power transmission performance as a millimeter wave antenna for plasma heating in nuclear fusion application. A Gaussian-like beam was radiated from the outlet of the launcher waveguide at 0.85 MW and with more than 95% efficiency over the steering angle range -12/spl deg/ to 12/spl deg/. The wave frequency was 170 GHz. The measured heat distribution along the waveguide length agreed with calculations.
