Simulation of Electromagnetic Resonance of IEMP in Cylindrical Cavity Using Particle-in-Cell Method

The electromagnetic resonance of IEMP in a cavity is studied by numerical modeling using 3-D Particle in Cell (PIC) codes combined with MCNP providing electron emission states. Two cylindrical cavity models of different sizes are computed, and then the condition of resonance is given. Moreover, the distribution of radial electronic field along the axial direction, as well as the distribution of electrons in the cavity is analyzed.
