| Abstract(in English) | In recent years, the office, home and so on are equipped with various electric and electronic devices. Electromagnetic waves that are radiated from these devices, reflect on the wall of the building or penetrate to the wall from outside, then they interfere to the other device. It's necessary to decrease the reflection and transmission by the concrete wall. In this paper, we analyzed the reflection and transmission characteristics of dome shape surface wall by the FD-TD method. Its surface has asperity form that newly proposed. As a result, we obtained that the dome shape surface wall consumed a power of electromagnetic wave in the wall more than a plain wall. Then the dome shape surface wall can oppress reflection and transmission. |
