| description | MAXWELL equations of electromagnetism are hyperbolic partial differential equations with real characteristic values as the non-viscous Euler equations of hydrodynamics, so the same mathematical characteristic makes it possible to apply computational fluid dynamics(CFD) techniques into computational electromagnetism(CEM) to get high precision electromagnetic fields. The finite volume time domain method(FVTD) is used in this paper, where flux vector computed by MUCSL scheme and Steger-Warming splitting method, unsteady time marching computed by 4 steps Runge-Kutta method, and the treatment of electromagnetic boundary conditions using the same techniques as in CFD. In the end, through the numerical simulation of electromagnetic scattering of wideband pulse wave, perfect conductor, media coated conductor and complex shape objects, it demonstrated that FVTD method based on CFD can calculate objective electromagnetic characteristic with a better precision. |
