Terahertz metamaterial waveguides: a platform to create the next generation of compact THz devices

该项目将通过利用超材料，能够以新的方式控制光的人造复合材料，制造基于太赫兹波导的设备。该项目将建造空芯超材料波导，目前刚性波导的大尺寸（几毫米）将减少到几十微米。该项目将展示使用这些新型波导的可调谐光谱滤波，从而实现世界上第一个基于空芯波导的超材料设备。其结果将对下一代太赫兹器件、高分辨率成像和高灵敏度生物传感器产生深远影响，这些器件是生物学、医学、法医学和公共安全等许多学科不可或缺的工具。

This project will make terahertz waveguide-based devices by exploiting metamaterials, man-made composite materials capable of controlling light in new ways. This project will build hollow-core metamaterial waveguides, where the large dimension (a few millimetres) of current rigid waveguides will be reduced to a few tens of microns. This project will demonstrate tuneable spectral filtering using these novel waveguides, leading to realisation of the world's first hollow-core waveguide-based metamaterial device. The outcome will have a profound impact on the next generation of terahertz devices, high resolution imaging and high sensitivity biosensors, which are indispensable tools for many disciplines including biology, medicine, forensic and public safety.
