In this study, we focus on deterioration in the shield property caused by penetrating a power wire through a transfixion hole. The shield structure of circular transfixion hole filled the space between the cable and the penetration part with dielectric and magnetic loss material is proposed, and shield property is evaluated by FDTD method and measuerment. As a result, it is confirmed that shield property decreases in case of penetrating a power wire through a circular transfixion hole compared with that of only circular hole, because this structure becomes circular coaxial line. Moreover, dielectric and magnetic loss material is filled in the space between the cable and the penetration part, it is clarified that shield property is improved about 20dB. Therefore, the effectiveness of this proposed structure to real transfixion hole can be confirmed quantitatively.
