Abstract :
Physical characteristics of a dc-biased single-surface multipactor are investigated theoretically, and a novel scheme of the multipactor using a photonic crystal cavity resonator to maximize insulation gap distance is introduced. A fixed rf phase minimizing rf electric field is analytically obtained, which is universal for any surface material. With an assumption of zero initial velocity, analytical derivations and a parametric map for the phase locking are presented. In the map, the second-order multipactor by a bifurcation of a stable fixed point appears, even though the premature impact is completely excluded artificially. This distinctive phenomenon is demonstrated by a three-dimensional particle-in-cell simulation.
