Multipacting simulations for superconducting cavities and RF coupler waveguides

Multipacting (MP) has recently received a renewed interest in the community of superconducting RF. In this paper, I will overview the developments of MP simulations for SRF cavities and RF couplers, summarize the simulation results, compare experiment results with simulation predictions and examine the algorithms. After identifying the discrepancy between the predictions and experiments, suggestions are given to further improve the simulations.
