Description
Summary:Based on the transcendental dispersion relation of the azimuthally symmetric mode which propagates along the surface of an inhomogeneous and collisional plasma layer coated cylindrical metallic surface, the influence of plasma parameters and metallic surface geometric size on propagation constant, radiation enhancement intensity, and wave energy loss properties is investigated. Theoretical calculation results indicate that there is a resonance at the point ωpe/ω = 1; near this point, the propagation constant of the symmetric mode exhibits extraordinary characteristics, the radiation enhancement intensity reaches a maximum at the point (ωpe/ω = 1.05, ν/ω = 1), and the wave energy loss reaches a maximum at the point (ωpe/ω = 1, ν/ω = 0.006). These theoretical results may have a potential application value in microwave enhanced radiation and high resolution image processing.
