The cold quality factor of magnicon on resonator in the rotating TM/sub n10/ mode and compared with its equivalent for the static mode

摘要

The field distribution of the magnicon operating in a rotating TM/sub n10/ mode in the cylindrical cavity is different from that in a static mode, and so respectively are expressions of the stored energy in the cavity, time-average dissipating power and cold quality factor, et al., under the same amplitude of the electrical fields, in the above-mentioned two modes. By means of the rotating and static field distribution expressions and the integrated Bessel function, these expressions for the rotating and static mode are deduced. In a first approximation, the average value g/spl circ//sub n/ and q/spl circ//sub n/ of the coefficient g/sub n/ and q/sub n/ are used for g/sub n/, and q/sub n/ in these formulas in the different range of n, such as g/spl circ//sub n/=1.5/spl isin/(0>n>8), g/spl circ//sub n/=1.4/spl isin/(7>n>12), and g/spl circ//sub n/=1.3/spl isin/(11>n>20). The corresponding average q/spl circ//sub n/ is also known. The deduced expressions of static cold quality factor are different from what are widely adopted now.
