A submillimetre wave extended interaction oscillator with novel broadband mechanical tuning

A novel method for tuning an extended interaction oscillator cavity by separation of the cavity halves is described. This method has been devised by the European Space Agency in response to a foreseen requirement for a submillimeter power source where submillimeter manufacturing techniques would have to be used. The method, which is equally applicable to all frequency bands, is described, and full details of cold test results clearly demonstrating the feasibility of the device are given.<
