Multipactor Analysis by Exploiting Kadane's Method

Multipactor is nowadays crucial when analyzing the final performance of satellite communication systems, as the critical components of these systems must meet demanding high-power specifications. Therefore, having access to fast and reliable multipactor simulations is of paramount importance for the radio frequency (RF) design process. This paper describes the Coarse method as a technique enabling faster predictions for time-varying signals, but also highlights the limitations of the method when analyzing long signals. In this work, the capabilities of the Coarse method are expanded by introducing the Kadane's search algorithm, which allows to identify the multipactor critical sequence of long signals with a limited CPU effort.
