Inserción de corrugaciones en filtros de microondas para reducción de multipactor Abstract: The multipactor effect poses a significant challenge in RF and microwave high-power devices like combline filters, affecting signal integrity and device performance. In this paper, we propose employing a corrugated surface profile to mitigate this effect. Through numerical simulations, we demonstrate that the introduction of a corrugated surface, significantly suppresses the onset and propagation of multipactor discharges within the filter structure. The corrugated profile effectively disrupts the conditions conducive to electron avalanche formation, thereby increasing the breakdown threshold level and reducing the likelihood of multipactor-induced signal degradation. Moreover, we explore the influence of various geometric parameters of the corrugated profile on the suppression of multipactor effect, providing insights into the optimal design considerations for mitigating this phenomenon. Our findings not only offer valuable guidance for the development of robust and reliable combline filters, but also contribute to the broader understanding of multipactor suppression techniques in RF and microwave high-power applications. |
