| Abstract(in English) | In recent years, low-frequency magnetic field noise generated from high power equipment has become a problem. Electromagnetic (EM) shielding materials are used to reduce the noise, but when used in high power equipment, EM shielding materials that have a heat ventilation effect are required. In this study, we placed transmission coils in a metallic enclosure as magnetic field generation source and investigated the leakage magnetic field from the metallic enclosure. Next, based on the magnetic field distribution on the opening surface, EM shielding materials with ventilation holes were made, and the magnetic field leaking from the EM shielding materials were evaluated. |
