Abstract :
Resonant frequencies and coupling coefficient between two combline cavities, in the presence of other cavities, are obtained accurately using mode matching technique. The effect of iris dimensions and position on the electric and magnetic coupling is rigorously investigated. The corresponding data for two isolated cavities are included for comparison.
