摘要
吸波材料是武器装备的重要材料之一,目前朝着"厚度薄、密度低、频段宽、吸收强"的方向发展.本文综述了吸波材料的最新研究方法与进展,并提出了现有研究中存在的不足及进一步研究的方向.目前吸波材料的主要研究方向是制备纳米复合吸波材料,对吸波材料进行表面改性或掺杂改性,以及改变材料的微观形貌和结构设计等.然而现有的研究集中在常规吸波材料上,以摸索性的应用研究为主,缺乏理论的指导和突破性的创新.进一步的研究应以电磁波吸收理论为基础,开发纳米复合吸波材料以及具有结构设计的纳米复合吸波材料,并大力开展智能吸波材料与结构以及超材料吸波材料的研究与开发.
Electromagnetic wave absorbers （EMWAs） （i.e. microwave wave absorbers） are important materials for military equipment. Ideal EMWA should exhibit thin matching thickness, low density, broad bandwidth, and strong EM absorption. The recent advances of EMWA were reviewed in this study, and the shortcomings in current studies and approaches for further researches were suggested. Recent researches on EMWAs are mainly focused on the preparation of nanocomposites, doping or surface modification, and changing the micro-morphology and structures of EMWA. However, these studies concentrated on traditional EMWAs and applied researches, which lack of theoretical guidance and breakthrough innovations. Further investigations should pay more attention on the nanocomposites and nanocomposites with structure designing under the guideline of electromagnetic wave theory. Moreover, smart materials and structures and metamaterials are promising EMWAs with excellent properties.
