Study on the Z-FDTD for Electromagnetic Scattering Characteristics of Two-dimensional Inhomogeneous Plasma Sheath

This paper is based on the hypersonic vehicle and its plasma flow field, the interaction mechanism between plasma sheath and electromagnetic (EM) wave is studied. The EM scattering characteristics of hypersonic vehicle with its plasma sheath are analyzed by the RCS. On this basis, combined with Z-transform finite-difference time-domain method (Z-FDTD), some theoretical results of scattering characteristics of electromagnetic wave by plasma sheath are summarized, which have important significance for stealth and radar detection of high speed targets.
