@@@@Based on the Maxwell equations and boundary conditions, the dispersion relation of the surface plasmon, which is excited by electrons moving above the metal surface, was theoretically analyzed. And the two cases: the electrons moving above the bulk metal and above the metal film, were studied respectively. Also, the particle-in-cell code was carried out to simulate above these two cases, and the results agreed well with the theoretical analysis.
