论文摘要
提出了使用Glide对称销子状的无接触式跨面的可重新配置的毫米波人造波导，以便在切换操作中实现低损失和高功率处理能力。由于滑行对称性的出色行为，元结构既被用作宽带EBG材料，以限制指南中的田地，也可以用作填充指南本身的低分散引导介质。通过调整元信息之间的位移来实现重构性。较高的位移可以在波导内传播，而较低的位移会抑制它。因此，设计了两态的重构性，使设备可以充当V波段中的开关开关。特别是，分散分析突出了这种技术实现在55-66 GHz频率范围内运行的开关的潜力。还描述了一个完整的设计，包括匹配机制和WR15喂食，并显示出$ s_ {11} <-10 $ db带宽，从57.4到62.8 GHz。在“ OFF”状态下，开关隔离大于65 dB，在“ ON”状态中，插入损失在整个工作频率范围内都优于0.7 dB。还讨论了两个相邻波导之间的隔离，以评估该设备在交换网络中的集成。
A reconfigurable millimeter-wave artificial waveguide using glide-symmetric pin-like contact-less metasurfaces is proposed in order to enable low loss and high-power-handling capability in switching operations. Thanks to the remarkable behaviour of glide symmetry, the meta-structures are used both as wide-band EBG material to confine the field in the guide and as low-dispersive guiding medium filling the guide itself. The reconfigurability is achieved by adjusting the displacement between the metasurfaces. A higher displacement enables propagation within the waveguide and a lower displacement suppresses it. A two-state reconfigurability is therefore designed, allowing the device to act as an on-off switch in the V-band. In particular, a dispersion analysis highlights the potential of such technology to achieve switching operating over a 55-66 GHz frequency range. A complete design including matching mechanism and WR15 feeding is also described and shown to exhibit a $S_{11}<-10$ dB bandwidth from 57.4 to 62.8 GHz. In the "off" state, the switch isolation is better than 65 dB and in the "on" state, the insertion losses are better than 0.7 dB within the entire operating frequency range. The isolation between two adjacent waveguides is also discussed to assess the integration of such a device within a switching network.
