Outline of Final Research Achievements |
Shielding effect of periodically/non-periodically perforated metal plate for near field is studied theoretically and experimentally. For electric power unit case, metal plate is preferable for magnetic field shielding, however, the plate with holes is required for ventilation. In this study, the shielding effect with metal plates with holes are estimated theoretically and confirmed by experiments. The transmitted fields from the holes depend on the holes size and the incident magnetic fields to the holes. The radiation from the holes is weak, if incident fields to the holes are weak. The shielding of the metal plate with holes is effective when the incident fields are weak at the holes.
