摘要
Coaxial O-type Cerenkov devices usually operate in the quasi-TEM or TM01 mode, but the power capacity characteristics of these modes in coaxial slow-wave structures (SWSs) have not been published thus far. This paper presents numerical studies of the power capacity characteristics of the quasi-TEM and TM01 modes in coaxial SWSs. The results suggest that the power capacity of the TM01 mode is not significantly higher than that of the quasi-TEM mode, unless the distance between the inner and outer conductors is less than a critical value. A comparison of the power capacities of the TM01 mode in coaxial and hollow SWSs is reported for the first time. When the distance between the inner and outer conductors of coaxial SWSs is small enough or the outer radius is large enough, the power capacity of the TM01 mode in coaxial SWSs is higher than that of the TM01 mode in hollow SWSs with the same outer radius.
