本研究探讨了在sub-6 GHz下基于1位双线极化变容的超表面设计的性能。采用改进的粒子群优化算法确定元件的几何形状，使反射损耗和相位误差最小，交叉极化隔离最大。在3.3至3.7 GHz范围内，单元单元可以单独寻址并具有独立的极化控制。一个由48 x 16单元组成的原型已经被制造出来，用于部署在可重构的智能地面辅助无线通信信道探测活动中。
This work explores the performance of a 1-bit dual-linear polarised varactor-based metasurface design at sub-6 GHz. A modified particle swarm optimisation algorithm was utilised to determine the element geometry resulting in minimum reflection loss and phase error, and maximum cross-polarisation isolation. Unit cells may be individually addressed and with independent polarisation control over 3.3 to 3.7 GHz. A prototype consisting of an arrangement 48 x 16 unit cells has been fabricated for deployment in a reconfigurable intelligent surface-aided wireless communication channel sounding campaign.
