This project will explore the design, simulation, fabrication and testing of materials and structures for the focusing, filtering and steering of terahertz radiation. The terahertz region sits between microwave and infrared in the electromagnetic spectrum but is reliant on bulky, and often expensive, lenses and parabolic mirrors for beam manipulation. This reliance poses significant challenges for the development of low cost, compact systems. In this project, research will be conducted to identify new materials and fabrication techniques for both diffractive and refractive optical components. A long-term goal is to introduce photosensitive micro- and nanoscale objects in/on to the fabricated THz optical components, enabling active beam control. This research could have an impact on a wide range of emerging applications for terahertz radiation including next-generation wireless communications, autonomous vehicle control, security scanning and bio-identification.

该项目将探索设计、模拟、制造和测试用于聚焦、过滤和操纵太赫兹辐射的材料和结构。太赫兹区域位于电磁波谱中的微波和红外线之间，但依赖于庞大且通常昂贵的透镜和抛物面镜进行光束操纵。这种依赖性对低成本、紧凑型系统的开发提出了重大挑战。在这个项目中，将进行研究，以确定衍射和折射光学元件的新材料和制造技术。长期目标是在制造的THz光学元件中/上引入光敏的微米和纳米级物体，从而实现主动光束控制。这项研究可能会对太赫兹辐射的广泛新兴应用产生影响，包括下一代无线通信、自动驾驶车辆控制、安全扫描和生物识别。
