基于连通矩形谐振环结构的双波段左手材料吸波器
Dual Band Left-Handed Material Absorber Based on Connected Rectangular Resonant Ring Structure
摘要
Abstract
A dual band connected rectangular resonant ring structure is proposed,which is designed to work in the case of parallel incidence of electromagnetic wave. Making full use of the strong resonant loss properties of electro-magnetic metamaterials,by designing the electromagnetic parameters of left-handed materials reasonably and using CST to optimize the structure,a wave absorver with better absorbing effect is designed to make the two absorption peaks located in the 5.41 GHz and 7.11 GHz frequency bands and the absorption rate is higher than that of the con-ventional carbon membrane absorber. A left-handed material absorber of dual band connected rectangular resonant ring structure is fabricated and its propagation characteristics are measured. The experimantal results show that the experiment agrees well with the simulation results. The absorber can be used as attenuator for microwave circuit to replace the structure of traditional absorber.关键词
