Resumen:

One of the main goals of the current microwave space components' designers is that they can withstand the increasingly higher RF power requirements that must be considered at the output stages of transmitters. In this work, we propose a periodically grooved metallic surface profile that can significantly reduce the occurrence of multipactor effect in microwave components under vacuum conditions. The proposed technique has been applied to the top and bottom surfaces of a rectangular waveguide, and the multipactor power threshold with and without periodically grooved surfaces has been compared.
