由於無線電磁波及家電產品的普及使用，室內的電磁環境污染日益嚴重。隨著暴露於電磁場的時間 增加，容易產生電磁環境的健康問題。本硏究的主要目的是降低室內電磁環境的污染，提出將建築物外 壁材賦予電磁波屏蔽性能及內壁材賦予吸收性能之解決對策與敘述電磁波屏蔽與吸收的設計方法。並分 析出電磁波屏蔽效果與材料之導電係數及厚度成正比，電磁波吸收性能與適當的材料厚度及複數相對介 電係數有互相依存之特性。

The indoor electromagnetic environmental pollution is serious day by day, as a result of the popularization use of the wireless devices and the domestic electric apparatus. If the living environment is exposed in electromagnetic radiation for a long time, health and comfortableness of the indoor electromagnetic environment may be destroyed. The purpose of this research tried to reduce the pollution of the indoor electromagnetic environment. This research proposed that the outside wall material offer the electromagnetic wave shielding performance and the inside wall material offer the electromagnetic wave absorbing performance. It was found that electromagnetic wave shielding performance was in direct proportion to thickness and conductivity of the material, electromagnetic wave absorbing performance depended on the suitable thickness and complex permittivity of the material.
