Abstract

Abstract

The one-dimensional system generated electromagnetic pulse(SGEMP) boundary layer is simulated by PIC code of quasi-first principle. The SGEMP effects of monoenergetic emission model are studied—the photoelectrons are emitted normally at 3.3×10²⁰m^-2·s^-1 all with 2 keV energy from infinitely large dielectric plane while positive charges are left on the plane. When the steady state is reached, the maximum distance the electrons travel is oscillating between 5.8 cm and 7.5 cm, the charge density at z=0 is oscillating within (6.0-9.0)×10^－6C/m³ and electric field at the surface is 50-55kV/m. The build-up time of quasi-steady state is 14.0 ns. The simulation results of steady state accord with the theoretic results, and the simulation results could image the forming process and the adiabatic oscillation of the steady state more clearly than the theoretic results. The modeling by PIC code to study SGEMP effects is validated.
