Multipactor effects can be analyzed with VSim for microwave structures, such as waveguides and coaxial cables.
Multipactor in the vacuum has been considered for high-power components.
In practice, fringing fields generated around slots tend to significantly increase the voltage necessary to induce multipactor [34].

WEPA-2: Multipactor Breakdown Prediction in Rectangular Waveguide-based Components
Critical aspects ofthe RF mechanical and thermal design include the small waveguide size and the relatively high power requirement resulting in the associated design challenges to achieve low losses sufficient multipactor threshold and to manage the heat dissipation.
Given above reasons, multipactor is a critical issue in the design of microwave devices for space application [2], which has attracted much more attention from the scientific communities [3,4].
The findings from the on-going TRP Novel Investigation in Multipactor Effects in Ferrites and Dielectrics Used in High Power RF Space Hardwareshall be used to improve the prediction of the breakdown.

Design Data for the Control of Multipactor Discharge in Spacecraft Microwave and RF Systems
The dielectric resonator structure is much smaller than a cavity counterpart, and thus is more susceptible to power-induced failure, such as overheating, arcing or multipactor discharge.
