A multiband absorber fabricated from stereo frequency selective structures (FSSs) is presented herein. The proposed absorber is composed of a lateral spilt loop intersected by four standing closed loops. The absorber exhibits pentaband electromagnetic (EM) wave absorption at normal incidence, as well as an angle‐dependent multiband absorption with high absorptivity at large incident angles (>80°) for both transverse electric and transverse magnetic polarizations. The complicated structure, including the stereo resonators and dielectric substrate, is fabricated using one‐step forming method of multimaterial hybrid microdroplet jetting modeling (MHMJM) technology. The results suggest that this design strategy has great potential in constructing stereo FSSs with unique characteristics.

基于立体频率选择结构的3D打印多频带吸收器

本文提出了一种由立体声频率选择结构（FSS）制成的多频带吸收器。拟议中的吸收器由一个横向的溢流环组成，该溢流环与四个直立的闭合环相交。该吸收器在垂直入射时表现出五带电磁（EM）波吸收，并且在横向入射和横向磁极化时，在大入射角（> 80°）时具有高吸收率的角度依赖性多波段吸收。使用多材料混合微滴喷射建模（MHMJM）技术的一步成型方法来制造包括立体谐振器和介电基板在内的复杂结构。结果表明，该设计策略在构建具有独特特征的立体声FSS方面具有巨大潜力。
