The objective of this work is to study the scattering characteristics of multiple coatings of plasma coated cylinders and spheres. Both dielectric and conducting cases are considered. The dielectric constant or the refractive index of plasma has a significant impact on the radar cross-section (RCS) of the geometries under study. Using experimentally reported plasma dielectric constants obtained from collision frequency and plasma frequency, we observed that in some cases, depending on the choice of parameters, we see reduction of RCS whereas in others the RCS is enhanced. As a result, designers need to apply plasma with care when it is used as an absorber for RCS reduction. The results of this work are expected to be applicable to the development of plasma stealth technology, which has gained a lot of interest lately.
