以往无线通信的性能提升，往往依赖扩大天线阵列规模或采用机械结构实现主动波束转向。虽然有效， 但这类方案也会增加成本、系统复杂度及故障风险。研究团队认为，若不从电磁波传播方式本身进行改 进，6G在太赫兹频段的实际部署可能面临困难。 （文章来源：科技日报） 为此，研究团队引入拓扑光子学概念，通过人工结构设计，使光或电磁波沿"受保护"的路径传播，即便 遇到缺陷或急转弯也能保持稳定。 据最新一期《自然·光子学》杂志报道，来自新加坡、法国和美国的科研团队借鉴拓扑光子学理念，设 计出一种片上紧凑型天线。其能利用芯片微结构实现高效辐射，处理信息密度极高的太赫兹信号，显著 提升数据传输速率，为未来6G无线通信提供重要基础。 实验结果显示，该天线实现的数据传输速率比当前最先进的太赫兹器件高出数百倍。值得注意的是，所 有功能均通过被动结构实现，控制机制直接嵌入芯片几何设计之中，无需额外的机械运动部件或复杂的 主动控制系统，这有望显著降低运行成本并提高可靠性。 未来的6G网络预计可实现每秒1太比特的数据速率，这相当于在1秒内传输一部中端智能手机约一半的 存储容量。要达到这样的速度，无线系统必须在远高于当前5G的太赫兹频段运行，但相 ...
