In this paper, a dual-band metamaterial absorber (MMA) ring with a mirror reflexed C-shape is introduced for X and Ku band sensing applications. The proposed metamaterial consists of two square ring resonators and a mirror reflexed C-shape, which reveals two distinctive absorption bands in the electromagnetic wave spectrum. The mechanism of the two-band absorber particularly demonstrates two resonance frequencies and absorption was analyzed using a quasi-TEM field distribution. The absorption can be tunable by changing the size of the metallic ring in the frequency spectrum. Design and analysis of the proposed meta-absorber was performed using the finite-integration technique (FIT)-based CST microwave studio simulation software. Two specific absorption peaks value of 99.6% and 99.14% are achieved at 13.78 GHz and 15.3 GHz, respectively. The absorption results have been measured and compared with computational results. The proposed dual-band absorber has potential applications in sensing techniques for satellite communication and radar systems.

本文提出了一种具有镜像反射 C 形的双频超材料吸收器（MMA），用于 X 和 Ku 波段传感应用。所提出的超材料由两个方形环形谐振器和一个镜像反射 C 形组成，在电磁波谱中呈现出两个独特的吸收带。双频吸收器的工作机制特别表现出两个共振频率，并且使用准 TEM 场分布对吸收进行了分析。通过改变金属环在频谱中的尺寸，可以实现吸收的可调谐性。使用基于有限积分技术（FIT）的 CST 微波工作室仿真软件对所提出的超吸收器进行了设计和分析。在 13.78 GHz 和 15.3 GHz 处分别实现了 99.6%和 99.14%的两个特定吸收峰值。吸收结果已经进行了测量并与计算结果进行了比较。所提出的双频吸收器在卫星通信和雷达系统的传感技术中有潜在的应用。
