Research on the scattering characteristics of fully ionized dusty plasma for FPL model

Starting from Boltzmann’s approximate equation, the Fokker-Planck-Landau (FPL) collision model of dusty plasma is derived. The expression of the electrical conductivity of the dusty plasma under the collision condition of the fully ionized FPL is obtained by combining the collision effect and charging effect of the dusty plasma. Using Z transform finite-difference time-domain (Z-FDTD) algorithm to analyze the scattering characteristics of metal cylinder coated with dusty plasma with different dusty plasma parameters. Results show that with the increase of electron density, size and density of dust particles in dusty plasma, the double-station RCS of metal cylinder coated with dusty plasma also increases. These findings provide references for studying the electromagnetic scatting of dusty plasma.
