✦ Synopsis

The power transmission problem of a coaxial line probeto-circular wa¨eguide for TM multimodal excitation is rigorously treated 0 n using the conser¨ation of complex power technique. The o¨erall scattering matrix of the coaxial line probe-circular wa¨eguide is deduced. Computed results for the reflection coefficient of the coaxial line probe are then compared with the experimental results, and they agree well. The power distribution of ¨arious order modes excited in a circular wa¨eguide is in¨estigated as a function of the probe length. Analysis shows that the power of the highest order TM propagation mode excited in the 0 n circular wa¨eguide is usually the largest.
