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

点击翻译按钮获取中文摘要

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.
