    El método de la ecuaciones de patrón (PEM) han sido extendidospara resolver problemas de scattering en ondas electromagnéticas por medio de partículas con superficie de impedancia mista anisotrópica. Luego, las condiciones de frontera de impedancia anisotrópica se imponen en la superficie lateral de la partícula, y condiciones de frontera de impedancia isotrópica se imponen en caras finales de la partícula. El método se formula para cuerpos axialmente simétricos.Se presentan las características del scattering de los cuerpos con superficies laterales artificiales suaves y duras. Se lleva a cabo la comparación de los resultados con los que se obtienen con otros métodos. También se presenta el análisis de la tasa de convergencia del algoritmo numérico PEM y la precisión de los cálculos numéricos. Finalmente se hace la comparación de nuestros datos con los resultados numéricos obtenidos antes con el PEM en ausencia de la impedancia anisotrópica.

    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.
