The pattern equation method (PEM) has been extended to solve the scattering problems of electromagnetic waves by particles with mixed anisotropic surface impedance. Thus, the anisotropic impedance boundary conditions are imposed on lateral surface of the particle, and isotropic impedance boundary conditions are imposed on end faces of the particle. The method is formulated for axially-symmetric bodies. The scattering characteristics of the bodies with artificially soft and hard lateral surfaces are presented. The comparison of the results with those obtained by other methods is carried out. The analysis of convergence’s rate of numerical algorithm of the PEMand accuracy of numerical calculations are presented. Comparison of our data with numerical results obtained earlier by the PEM in absence of an anisotropic impedance is carried out.
