Analysis of Electromagnetic Scattering of Cavities with Nonuniform Plasma Coating
The radar cross section of cavities coated with nonuniform plasma is analyzed by using the shooting and bouncing ray (SBR) method in this paper. The curvilinear triangular patches are adopted to model the surface of arbitrarily shaped cavities, so that it can meet the practical needs of engineering. The nonuniform plasma slab used to coat cavities is modeled by a series of subslabs, in which the plasma parameters are assumed to be constant. Then the reflection coefficients of the rays to coated cavity are calculated and then applied in calculating the RCS of cavities. The numerical results of the cavities coated with nonuniform plasma indicate that the parameters of the plasma slab can affect the RCS effectively.
