Abstract
Perfectly Matched Layer (PML) is modeled by Split-Field FDTD (SF-FDTD) in order to simulate Radar Cross Section (RCS) of a plasma slab. PML is used as an absorbing boundary, and discrete plane wave (DPW) is employed to generate plane wave. DPW method has a power isolation of 300 dB between scattered-field and total-field regions. The Dispersive media is modelled by shift-operator FDTD. Finally, by using Near-to-Far Field Transformation, all fields are transferred to far field region to calculate RCS.
