电磁波吸收建筑材料的应用研究进展

Recent Progress in Electromagnetic Wave Absorbing Building Materials

应用电磁波吸收建筑材料是改善建筑空间电磁环境的有效方法。随着电磁辐射污染日益严重,吸波建材已逐渐成为研究热点。综述了近几年吸波建材的研究方法与研究现状,将吸波建材归纳为吸波剂填充型和结构设计型两大类,并分别进行评述,提出了现有研究中存在的一些问题以及进一步的研究方向。"轻、薄、宽、强"仍然是吸波建材的发展方向,同时电磁波损耗机理还有待进一步研究。

Application of electromagnetic wave （EMW） absorbing building materials is an effective method to improve the electromagnetic environment of architectural space. And the EMW absorbing material has been a hot area of research in recent years, as the electromagnetic radiation pollution increasing seriously. The recent advances and research methods of EMW absorbing building materials are reviewed in this paper. The materials are summarized as two major categories：filling absorbing agent and structure design, and then the shortcoming of current studies and approaches for further researchers are suggested after the review. Design of the ideal absorbing building materials with the characteristics of low density, thin matching thickness, broad bandwidth and strong microwave wave absorption, is the main direction, and the mechanism of wave absorption should be researched in depth.
