Based on the finite element method (FEM) in the frequency domain and particle-in-cell approach in the time domain, a hybrid domain multipactor threshold prediction algorithm is proposed in this paper. The proposed algorithm has the advantages of the frequency domain and the time domain algorithms at the same time in terms of high computational accuracy and considerable computational efficiency. In addition, the compute unified device architecture (CUDA) acceleration technique also can be employed to further enhance its simulation efficiency. Numerical examples are carried out to demonstrate the effectiveness of the proposed algorithm. The results indicate that the multipactor threshold can be accurately predicted and the computational efficiency can be improved.
