Abstract :
In this paper the multipactor power threshold in arbitrary complex components based on rectangular waveguide technology is investigated. The two required computations when studying such a phenomenon have been performed: calculation of the electromagnetic fields inside the component and determination of the multipactor breakdown onset itself. A full multipactor model is described and tested for a particular set of devices for which experimental measurements have been also performed. The good agreement between the predicted breakdown values and the experimental results shows the validity of the approach followed.
