Research Abstract

An existence of an electromagnetic surface wave is confirmed experimentally and an oscillator which is using this wave is developed in X-band (oscillation frequency is controllable by beam voltage). The electromagnetic surface wave is transmission mode which is in the vicinity of the periodic slow wave structure surface (for example corrugated metal surface). The existence of this wave had been pointed out analytically. The transmission on the corrugated metal surface of its wave is confirmed by the cold test. And, the characteristic of the interaction (Cherenkov instability and Smith-Purcell type instability) between this wave and electron beam is analyzed numerically. The oscillator is developed based on these results.
