“…The solution domain is truncated from the left and the right using the ABC. Different from the 2-D problem considered in [50], in this paper, a 3-D problem is solved by setting a thickness to the structure (the x direction which is not shown in Fig. 3) and placing the PMC boundary conditions on both sides in the thickness direction to reproduce the 2-D phenomenon in 3-D. A 25-GHz, 2.0-MV/m, and vertically (the y-direction) polarized plane wave with a tapered sinusoidal temporal profile is launched from the left boundary and propagates toward the right direction (the z-direction).…”

“…The plasma model adopted in this paper is a diffusion model that was originally developed in [46]- [50]. In the plasma fluid model, the PDF of a plasma species is integrated over the momentum space of the Boltzmann equation, which yields the macroscopic concepts of the particle number density n, the mean velocity u, and the mean energy E. By taking the first three moments of the Boltzmann equation, one can obtain the mass conservation equation (also known as the particle continuity equation), the momentum conservation equation, and the energy conservation equation.…”

Rapid plasma formation and evolution during highpower microwave (HPM) air breakdown in an HPM device produce a macroscopic plasma shield to the microwave transmission, which can severely limit the performance of the device. In this paper, the electromagnetic (EM)-plasma interaction and the HPM breakdown in air are modeled by a nonlinearly coupled full-wave Maxwell and plasma fluid system under conditions of high pressure and high collision frequency. The resulting multiphysics and multiscale system is solved by a nodal discontinuous Galerkin timedomain (DGTD) method, which is uniformly high order in both space and time. To demonstrate the capability of the DGTD method in the modeling of the HPM breakdown problems, the air breakdown and plasma formation in a metallic aperture are simulated, from which the underlining physical process can be interpreted and better understood.Index Terms-Air breakdown, discontinuous Galerkin time domain (DGTD), high-power microwave (HPM), nonlinear modeling, plasma fluid model, plasma formation, plasma shielding.

This paper proposes an improved algorithm, based upon an explicit finite difference scheme, in order to simulate the plasma breakdown induced by a monochromatic High Power MicroWave (HPM). The 3D coupled Maxwell-plasma equations are to be solved. We want to study with this model the geometry of the discharge and plasma formation at high pressure which may contribute to shield microwave sensors or circuits. Generally, the simulation of this kind of problem is very time-consuming, but by using the fact that the plasma evolution in time is slow relatively to the monochromatic source period, we can drastically reduce the simulation time. By considering this assumption, we describe in the paper a process which allows to obtain this important reduction. Finally, an example where we show the gain obtained in terms of computation time with our process is given to validate and illustrate the global work.
