The objective of this paper is to advance the state of the art in the characterization of the multipactor effect in dielectric materials. The materials studied are the most commonly used dielectrics in space applications, namely, Alumina, Rexolite, Rogers RT5870, Rohacell, Teflon, and Ultem 1000. In this paper, a new family of coaxial waveguide components, covering the $L$ - and $S$ -bands, with a wideband, low-pass response has been designed, and six different prototypes have been specifically optimized and manufactured. The six prototypes have then been used to simulate and measure the multipactor breakdown susceptibility charts for the six dielectric materials investigated. Finally, the simulation results are compared with the results of the measurement campaign indicating good agreement. [ABSTRACT FROM AUTHOR]

Multipactor effect is a resonant avalanche of secondary electrons induced by an RF electromagnetic field, which endangers high-power payloads on satellites and particle accelerator structures. The main goal of this letter is to present a multimodal network characterization of a multipactor discharge occurring in a bounded waveguide region. This will allow to perform a rigorous analysis of a complete passive component considering the presence of a discharge. In order to verify the present formulation, we have measured the power spectrum generated by a multipactor event excited in a simple microwave circuit based on rectangular waveguides, which has been compared with the theoretical results, obtaining good agreement.
