N2 - As the fundamental characteristics of microwave application, which is expected to be one of the useful technologies in the reduction reaction of iron oxide, electromagnetic anisotropic characteristics of electromagnetic materials in application of microwave are observed by micro-sized numerical high frequency electromagnetic computation. In assuming that the micro-sized unit structure is repeated in 3-dimensional directions and its size is much smaller than the electromagnetic wave length, the micro-sized electromagnetic field calculation using finite element method and jω method is carried out. In considering the bar shape and the cube shape as a micro-structure of electromagnetic material, the bar shape micro-structure has anisotropic characteristics, though cube shape micro-structure has isotropic ones. The generation of depolarization field within the micro-structure causes the difference of electromagnetic characteristics and the anisotropy.
