    Abstract

    The radar cross section reduction can be achieved by controlling the reflections from the surface of the structure. Plasma envelope is one of the ways to control the reflections and scattering from the surface. The problem of EM propagation within bounded plasma can be approximated as multi-layered dielectric problem. The overall reflection from an inhomogeneous plasma on a RAM covered conducting surface is discussed in this paper. The assumed structure is multi-layered, consisting of plastic, plasma, radar absorbing material and conductor. The propagation characteristic of the electromagnetic wave is analyzed using impedance transformation method. The dependence of reflection behavior of the multilayered structure on the plasma parameters is studied. It is shown that the absorption and its bandwidth are improved due to plasma inhomogeneity.
