摘      要：The Landau damping behavior in a cylindrical inhomogeneous warm magnetized plasma waveguide has been *** radial inhomogeneity for different characteristic lengths（L0） with strong spatial dispersion has been taken into *** analyses have been considered for two limits ωce 〈 ωpe and ωce 〉 ωpe. Due to the radial inhomogeneity of the plasma, all essential equations for studying the Landau damping are calculated in the Bessel–Furrier and differential Bessel–Furrier expansions. The dependence of Landau damping on the inhomogeneity, temperature and external magnetic field for electrostatic modes is scrutinized and described in detail through numerical calculations. The associated numerical results are presented and discussed.
