N2 - The high-power microwave (HPM) breakdown in air would result in a sharp increase of the number density of the plasma, which generates strong secondary electromagnetic (EM) fields that can cancel the incident fields and act like a macroscopic plasma shield. If such an air breakdown takes place in a HPM device, it will result in the so-called tail erosion and severely limit the performance of the device. In this paper, the EM-plasma interaction and the HPM air breakdown are modeled by a coupled nonlinear EM-plasma system, which is solved by a coupled nodal discontinuous Galerkin time-domain (DGTD) scheme. The air breakdown and plasma formation in a metallic aperture are simulated to demonstrate the capability of the DGTD method in the modeling of HPM breakdown problems.
