Description

Characterization of trapped-mode parameters in complex components typically requires substantial computational resources. Accurate acquisition of these parameters is crucial for elucidating component impedance characteristics and suppressing beam instabilities. To address this challenge, this paper proposes a parameter extraction method based on the particle swarm optimization algorithm(PSO), which establishes a multi-resonator wake potential fitting framework that enables efficient and accurate extraction of resonant frequencies, quality factors, and R/Q values.
