The structure can be regarded as a plasma antenna. To better reflect practical conditions, we consider inhomogeneous plasma covers, since laboratory and atmospheric plasmas are typically non‑uniform. Introducing anisotropy and inhomogeneity in the plasma coating enhances the tunability and flexibility of the radar cross‑section (RCS). We analyze the total axial magnetic field, the RCS, and the backscattering RCS (BRCS) under variations of incidence angle, wavelength, polarization, external DC magnetic field, and plasma inhomogeneity. For comparison, the system is also examined without plasma coating and without magnetic field, to highlight the role of anisotropic inhomogeneous plasma layers. The validity of the FE‑BI method is confirmed by benchmarking our results against the Perfectly Matched Layer (PML) technique.
