Title: Research on the FDTD Method of Electromagnetic Wave Scattering Characteristics in Time-Varying and Spatially Nonuniform Plasma Sheath
Authors: Wei Chen;Lixin Guo;Jiangting Li;Songhua Liu
subject: Finite-difference time-domain (FDTD)|radar cross section (RCS)|time-varying plasma|plasma sheath|stratified plasma

Publisher: IEEE
Abstract: 3-D time-varying and spatially nonuniform plasma is applied using the finite-difference time-domain algorithm in investigating the effects of electromagnetic (EM) wave scattering in the plasma sheath. The plasma sheath is stratified in space, and three types of electron density in time-varying forms are assumed. The characteristics of different time-varying forms are analyzed using radar cross section (RCS). In addition, the effects of RCS change with time at Sand L-bands are investigated using electron density as the time variable. In the condition of timevarying and spatially nonuniform plasma sheath, the attenuation of EM wave is affected by different time-varying regularities of electron density (n<sub>e</sub>). The RCS varying with time is related to the change rate of n<sub>e</sub>.
