Visual computing method of radar cross section for target coating with plasma

A computational electromagnetic model for target coating with plasma is presented, based on the assumption that plasma medium is cold, unmagnetized, collisional and inhomogeneous. In a high frequency region, the laminar flow plasma which shields target can be treated as layered plane media. In each layer, the plasma is equivalent to a uniform dielectric. Physics optics (PO) and Impedance boundary condition (IBC) are applied to calculating the backscattering field, which is implemented by visual Graphical electromagnetic computing (GRECO) method. Numerical results illustrate that the target coating with plasma is a valid measure to reduce the Radar cross section (RCS) of target. This conclusion has revealed a broad prospect for plasma stealth and anti stealth.
