Abstract: The problem of scattering of a plane electromagnetic wave incident on an impedance conducting cylinder cladded with a composite and anisotropic chiral medium sheath is solved. The formulas for calculating the electromagnetic fields in composite and anisotropic chiral media are derived. An analytic expression for the radar cross-section of an impedance cylinder coated with composite and anisotropic. chiral material is obtained by application of boundary conditions. Several typical results are also presented. -
