We propose a meta-waveguide, a component based on metamaterials and waveguides, to customize the phase and absorption of devices. This meta-waveguide integrated quasi-periodic metamaterial resonators with film resistors in the inner wall of the waveguide. The phase and absorption at multiple specified frequency points can be changed regularly by adjusting the resonators and film resistors. We analyzed the meta-waveguide structure and derived a transcendental equation, which revealed the physical mechanism of phase control. In addition, we propose an equivalent circuit model to explain the mechanism of absorption control. Then, a customized meta-waveguide that works from 90 to 100 GHz was designed, fabricated, and demonstrated.

我们提出了一种超波导，一种基于超材料和波导的组件，用于定制设备的相位和吸收。这种超波导集成了准周期超材料谐振器，波导内壁带有薄膜电阻器。通过调整谐振器和薄膜电阻器，可以有规律地改变多个指定频率点的相位和吸收。我们分析了元波导结构并推导出了超越方程，揭示了相位控制的物理机制。此外，我们提出了一个等效电路模型来解释吸收控制的机制。然后，设计、制造和演示了一个定制的元波导，可以在 90 到 100 GHz 范围内工作。
