This project will develop advanced measurement capabilities for applications exploiting the submm-wave (terahertz) frequency range (typically, from 0.3 to 3.0 THz). Specifically, it will research and develop new strategies to provide a step-change improvement in accuracy of traceable measurements using both wave-guided terahertz network analysers and free-space terahertz spectrometers. During the project, the PhD student will develop new high-precision alignment processes for waveguides and sample holders using optical techniques. These are expected to dramatically increase the accuracy, by several orders of magnitude, of current systems where the accuracy is currently limited by mechanical "pin and hole" alignment, leading finally to a new component connection strategy for submm-wave/terahertz communications and electronics, long sought by these industries. The project will make use of Europe's first 1 THz network analyser, installed in Prof Cunningham's research institute at Leeds, as well as the unique expertise of the Leeds team, which already has a very strong collaboration in this area with NPL. Ultimately, such developments are expected to be key to the adoption of the submm-wave frequency range by the communications sector, which is now beginning to expand into this frequency range. A wide range of electronic components, communications technologies and scientific instruments will thus be greatly facilitated by this research."

该项目将为利用亚毫米波（太赫兹）频率范围（通常为0.3至3.0 THz）的应用开发先进的测量能力。具体来说，它将研究和开发新的战略，以提供一个可追溯的测量精度的阶跃变化改进使用波导太赫兹网络分析仪和自由空间太赫兹光谱仪。在项目期间，博士生将使用光学技术为波导和样品架开发新的高精度对准工艺。预计这些将大大提高精度，通过几个数量级，目前的系统，其中的精度是目前有限的机械“销和孔”对齐，最终导致一个新的组件连接策略的亚毫米波/太赫兹通信和电子产品，长期寻求这些行业。该项目将利用安装在利兹Cunningham教授研究所的欧洲第一台1 THz网络分析仪，以及利兹团队的独特专业知识，该团队已经在该领域与NPL进行了非常密切的合作。最终，这些发展预计将成为通信部门采用亚毫米波频率范围的关键，现在通信部门正开始扩展到这一频率范围。因此，这项研究将大大促进各种电子元件、通信技术和科学仪器的发展。"
