提出了一种适用于F频段的基于单层图案化谐振结构的极化相关频率选择性超材料（MM）吸收体。本文介绍了该吸收体的设计、制作和测量。该吸收体在共振频率处的吸收特性对于入射波的不同偏振态具有单波段、双波段或三波段吸收的独特特性。计算的表面电流分布和功率损耗分布为进一步理解共振吸收的物理机制提供了依据。此外，在大范围的TE偏振斜入射下，获得了高吸收。因此，MM结构在高度柔性的聚酰亚胺膜上实现，使得吸收体适合于共形几何应用。该吸收体在偏振探测器和偏振器的发展中具有很大的潜力。
A polarization-dependent, frequency-selective metamaterial (MM) absorber based on a single-layer patterned resonant structure intended for F frequency band is proposed. The design, fabrication, and measurement for the proposed absorber are presented. The absorber's absorption properties at resonant frequencies have unique characteristics of a single-band, dual-band, or triple-band absorption for different polarization of the incident wave. The calculated surface current distributions and power loss distribution provide further understanding of physical mechanism of resonance absorption. Moreover, a high absorption for a wide range of TE-polarized oblique incidence was achieved. Hence, the MM structure realized on a highly flexible polyimide film, makingthe absorber suitable for conformal geometry applications. The proposed absorber has great potential in the development of polarization detectors and polarizers.
