【Abstract】 The Input Impedance of Semi-infinite Circular Waveguide excited by Single probe has been discussed in many references, but when the waveguide is fed by Multi-probe, the Mutual Impedance must be considered. In this paper the Expression of Mutual Impedance between two Coaxial-line Probes exciting in Semi-infinite Circular Waveguide is derived by Reaction Conception and Dyadic Green Function. Based on this, the formula of Mutual Impedance between two Probes deposited by Radial is given, and the Mutual Impedance of probes when there is only dominant mode transmitted in waveguide is calculated. At the end of the paper, the author discusses how Mutual Impedance is influenced by various factors.更多还原
