Abstract

In this paper, the spectral-element time-domain (SETD) method based on Gauss-Lobatto-Legendre (GLL) polynomials is applied to the solution of Maxwell´s Equations coupled to fluid model in 3-D microwave gas breakdown simulation of high-power microwave (HPM) propagation problems. The Galekin´s method is employed for the space discretization and the central difference scheme is used for time stepping. Numerical examples, compared with reported results demonstrate the ability and effectiveness of the SETD method for the analysis of microwave gas breakdown phenomena.
