Abstract

An innovative metamaterial (MTM)-based microwave absorber is proposed to feature a unique combination of rectangular and hexagonal resonators, tailored for multi-band absorption across the S, C, and X frequency bands. Built on a Rogers RT 3010 substrate, the proposed Metamaterial Absorber (MMA) demonstrates enhanced absorption efficiency, polarization independence, and angular stability. The absorber achieves multiple resonances at 3.36 GHz, 3.64 GHz, 5.06 GHz, and 6.36 GHz, with absorption values 90 %, 99.5 %, 99.7 % and 99.8 % validated through simulation analysis. The design evolution, progressing through resonator stages A, B, C, and D, highlights the impact of structural complexity on performance improvements. Experimental results align closely with simulations, showcasing minimal deviations due to fabrication imperfections. With its compact dimensions and high effective medium ratio (EMR), this MMA surpasses existing designs in multi-band functionality and efficiency, making it suitable for applications such as electromagnetic interference (EMI) shielding, radar systems, and wireless communication.

微波多波段超材料吸收器的设计与验证

提出了一种创新的基于超材料（MTM）的微波吸收器，它具有矩形和六边形谐振器的独特组合，可用于S， C和X频段的多波段吸收。基于Rogers RT 3010衬底，所提出的超材料吸收器（MMA）具有增强的吸收效率、极化无关性和角稳定性。该吸波器在3.36 GHz、3.64 GHz、5.06 GHz和6.36 GHz频段实现了多重谐振，通过仿真分析验证了吸波值分别为90%、99.5%、99.7%和99.8%。通过谐振器A、B、C和D阶段的设计演变，突出了结构复杂性对性能改进的影响。实验结果与模拟结果密切一致，显示了由于制造缺陷造成的最小偏差。凭借其紧凑的尺寸和高有效介质比（EMR），该MMA在多频段功能和效率方面超越了现有设计，使其适合电磁干扰（EMI）屏蔽，雷达系统和无线通信等应用。
