基于集总元件的超材料吸波器研究进展

摘要

基于集总元件的亚波长电磁超材料吸波器,因其厚度薄、吸波率强、谐振频率(或带宽)可调谐性和便于集成等优点越来越受到人们的关注.介绍了当前国内外基于集总元件的超材料吸波器的最新研究进展,并根据集总元件的种类对其进行分类,阐述了不同的吸波机理.这种可重构超介质吸波材料在能量搜集、信号源探测、(5G通信)电磁兼容、M IN O天线、舰船隐身等诸多前沿领域有广阔的应用价值.%Lumped elements-loaded electromagnetic metamaterial absorbers constructed by sub-wavelength structures ,have a-roused a surge of interest because of their unique advantages such as thin thickness ,strong absorption ,resonant frequency (or band-width) tunability and easy integration .This paper introduces the latest research progress of metamaterials absorber based on lumped elements at home and abroad ,and classifies them according to the types of lumped components ,together with different absorbing mechanisms .This kind of reconfigurable metamaterial absorbers have a wide application value in energy harvesting ,signal source de-tection ,(5G communication) electromagnetic compatibility ,MINO antenna ,ship stealth and so forth .
