Research on the Electromagnetic Scattering Characteristics of Plasma Sheath by Subdomain-Level DGTD Method

This paper developed a discontinuous Galerkin time-domain (DGTD) method to simulate the electromagnetic scattering characteristics of plasma sheath. Based on the domain decomposition technique, the computing domain is decomposed into multiple subdomains. To handle the dispersion properties of plasma in the time domain, we introduced the electrical flux density to construct an auxiliary differential equation (ADE). Finally, the scattering characteristics of a plasma sheath coated blunt cone is studied by the proposed method.
