N2 - A discontinuous Galerkin time-domain (DGTD) method is presented to simulate the coupled electromagnetic-plasma interactions in the modeling of high-power microwave (HPM) breakdown in air. For this multiphysics problem, the electromagnetic fields are governed by Maxwell's equations and the plasma is modeled as an electron fluid in continuum, which is governed by five-moment fluid equations. The non-Maxwellian electron energy distribution function (EEDF) is used to calculate electron transport coefficients and describe the non-equilibrium collision process between electrons and neutral particles. The coupled system is solved using the coupled DGTD method for a good accuracy and a high efficiency. A numerical example is presented to demonstrate the HPM pulse tail erosion when it travels through air at different pressures.
