Abstract :
In this paper, a simplified plasma limiter is modeled and simulated based on spectral-element time-domain (SETD) method. Maxwell Equations coupled to fluid model are proposed to describe the physics procession of the gas discharge and the mechanism of the plasma limiter. In order to solve the proposed PDEs, the Galekin´s method is employed for the space discretization and the central difference scheme is used for time stepping. Numerical examples demonstrate the ability and effectiveness of the SETD method for the design and analysis of these structures.
