可实现宽带吸波稳定性提升的新型电阻等离子吸波结构
Resistive plasmonic absorbing structures for stability enhancement of broadband absorption
摘要
Abstract
Broadband absorption performance in resistive metamaterial absorbers(MA)has always been dis-turbed by its ohmic sheet element.We propose a comprehensive scheme based on integrating resistive MA and plasmonic structure(PS)to enhance the stable absorption performance.Theoretical investigation indic-ated that the PS can inspire multi-resonance based on dispersion engineering,and that the localized electric field takes effect on the surface of the ohmic sheet accordingly.Simulation and experimental measurement demonstrated that the proposed resistive plasmonic absorbing structures(PAS)can achieve stable and highly efficient absorption within the frequency band from 7.8 to 40.0 GHz with the ohmic sheet ranging from 100 to 250 Ω/sq.In conclusion,the proposed integration of PS and resistive MA provides an efficient pathway to optimize performance for various applications.关键词
