摘　　要：This study analyzes the scattering of electromagnetic waves in a cold and uniform plasma-filled waveguide driven by an intense relativistic plasma beam under a strong magnetic field.The strong interaction of plasma with electromagnetic waves enables its potential use in different types of waveguides.The Helmholtz equation governs the boundary value problem,which is solved by incorporating the mode matching technique.Invoking the boundary and matching conditions and the derived orthogonality and dispersion relations in this scheme gives an exact solution to the scattering problem.The numerical results shed light on the occurrence of reflection and transmission and flow of power.The power flux is plotted against angular frequency and various duct configurations.The solution is completely validated through the benefit of analytical and numerical results.The investigation of this structure reveals not only its mathematical,but also its physical features.
