| الوصف: | This final report describes the effort to develop a discontinuous Galerkin time-domain (DGTD) method in the simulation of high-power microwave air breakdown phenomena, which are modeled by a coupled electromagnetic--plasma system. In the coupled system, the electromagnetic fields are governed by Maxwells equations and the plasma is modeled by the five moment fluid equations (Eulers equations). The non-Maxwellian electron energy distribution function (EEDF) is used to calculate electron transport coefficients and describe the non-equilibrium collision reactions between electrons and neutral air particles. The coupled Maxwell--Euler equations are solved by the DGTD method with high-order spatial and temporal discretizations, which are able to provide a sufficient resolution for the physical quantities in both space and time. Several numerical examples are presented to investigate the physical process and demonstrate the capability of the numerical method. |
