The electron emission boundary in bottom incidence cavity SGEMP simulation is introduced, and the peculiarity of the boundary in side incidence cavity SGEMP simulation is analyzed. By the employment of virtual-emission-surface, the electron emission boundary in side incidence cavity SGEMP simulation is realized. It is indicated that by using the method mentioned here one can achieve the electron emission boundary efficiently, both in flat and curved surface boundary condition, and the parameters and emission sequence of electron on the boundary obey the corresponding physical laws.
