| Abstract | (in Japanese) | (See Japanese page) |
| (in English) | The demand for shielding materials increases to suppress the wide-band radiation noise up to 30 MHz caused by high-speed switching devices. Authors had reported a wide-band 50-dB shielding laminated sheet composed of copper and magnetic sheets. In this study, the shielding performance of the sheet with N periodic apertures was evaluated by using an electromagnetic simulation model of the KEC method for the purpose of possessing its ventilation characteristics. The shielding performances converged with N=400 and were independent with the aperture area ratio when periodic interval is 50/√N. It is found that the 40-dB shielding performances with the aperture area ratio of 20% were obtained from 0.1 MHz to 10 MHz. |
