High-Order SO-DGTD Simulation of Radio Wave Propagation Through Inhomogeneous Weakly Ionized Dusty Plasma Sheath

On account of high-order hierarchical basis functions and shift operator concept, a technique of shift operator discontinuous Galerkin time domain is proposed to manage the electromagnetic problems of weakly ionized dusty plasma. Based on the numerical results of the multiphysics commercial software COMSOL and combined Lagrangian interpolation technique, the model of metallic blunt cone aircraft with weakly ionized dusty plasma sheath is established. The radio wave transmission characteristics of the sheath are analyzed under the conditions of varying speed and height of the flight.
