Analysis of 3D Magnetic Plasma Electromagnetic Scattering Based on Precise-Integration Time-Domain Method

A technique ground on precise-integration in time-domain (PITD) is applied to resolve the problem of electromagnetic scattering characteristics of magnetized plasma. The method combines the main equations of current density vector and electric field intensity vector with the principal equation of electric flux density D through the calculation method of auxiliary differential equations, and the equations are rewritten as linear ordinary differential equations for solving, and the coefficient matrix and integral terms in the equations are processed by the exact integration (PI) analysis and Gaussian integration methods, respectively, to obtain the component iterative equations for the solution of the ordinary differential equations. The technique is further implemented to analyze the galvanomagnetic scattering characteristics of a homogeneous time-varying magnetized plasma sphere through the simulation verification of a three-dimensional non-magnetized plasma sphere.
