The FEKO skin effect (“SK-card”) model for thin multilayer anisotropic materials can be used in a method of moments (MoM) solution to analyze multi-panel carbon-fiber composites when the tensor permittivity and conductivity of each layer are known. This is used to model some reinforced continuous carbon-fiber (RCCF) composites. The equivalent layer model of an RCCF composite and the tensor conductivity and permittivity have been obtained from the geometrical structure and electrical properties of the composite. The plane wave shielding effectiveness of single-panel and multi-panel RCCF composites are calculated using FEKO and results are compared with published literature. FEKO simulation results for the single-panel and multi-panel RCCF composites are in very good agreement with published finite element solutions. The plane wave magnetic shielding effectiveness inside a copper cube which has its front face replaced by a carbon-fiber composite is compared with another published MoM-GIBC solution. The agreement between FEKO simulation results and MoM-GIBC solutions is fair for single-panel composites, for multi-panel composites agreement could not be obtained. A monopole antenna with an anisotropic ground-plane is simulated and effects of the anisotropic conductivity on the radiation pattern are investigated. Anisotropic conductivity of the ground-plane did not have a strong effect on the radiation pattern of a monopole antenna.
