In this research, the scattering of long-wavelength electromagnetic waves from an elliptical cross-section in two different structures and configurations are investigated. The plasma column is exposed to the magnetic field B0.. In the first structure, the plasma column is covered by a dielectric layer, and in the second structure, a dielectric core is coaxial with the plasma column and placed in its center, and the plasma column is covered by a dielectric layer. By solving the equations of continuity, momentum transfer and Poisson's equation, as well as by using the boundary conditions regarding the electric field and potential, we calculate the electric field in different regions. The scattering and radar cross section are calculated. The figures related to the resonance frequency , the electric field , the scattering and radar cross section are plotted
