基于超材料设计实现C/Co复合材料的超宽带吸收
Ultra-wideband absorption of C/Co composites achieved through metamaterial-based design
摘要
Abstract
We synthesized C/Co composites via a facile one-step pyrolysis procedure and observed excellent di-electric dispersion properties at a 35 wt%filling concentration.At a thickness of 2.5 mm,the composites exhibit-ed a minimum reflection of-23.7 dB at 11.2 GHz,with a bandwidth of 3.8 GHz(RL≤-10 dB).To further im-prove their absorption performance,we optimized the macrostructure of the absorber using an all-dielectric meta-material design.The optimized design successfully extended the less than-10 dB absorption bandwidth to 15 GHz(7.0～22.0 GHz).Our results provide a useful reference for optimizing the preparation technology and structural design of high-performance microwave absorbers.关键词
