Magnetron resonance cavity for miniaturized atomic clocks

摘要

Many atomic clocks used magnetron type resonance cavity (MRC) as its microwave cavity because it can dramatically decrease the radical size of the atomic clock. In this paper, the electromagnetic character of MRC is investigated by a model based on transmission line theory. The formulas to calculate the resonance frequency, quality factor and magnetic energy filling factor are presented. The theoretical calculated results agree well with the electromagnetic software simulations and experiments.
