"This project develops a new type of antenna design for THz emitters based upon resonant tunnelling diodes. Conventional systems suffer from the THz wave being trapped within the substrate and subsequently extracted through the use of photonic crystal structures, horn antennas, etc. In this project we utilise the DRA concept to form a box shaped cavity with resonance designed to allow efficient extraction of the THz wave. The student will develop designs through simulation of dielectric resonator devices utilising resonant tunnelling diodes as the oscillating element. This will be collaborative with colleagues from University of Sheffield (DRA design), and Rohm Semiconductors, Japan (manufacturing and applications based aspects). The work will revolve around the development of device fabrication techniques (e-beam lithography, dry and wet etching) and device designs around the DRA concept. The student will develop test capabilities within the laboratory for both electrical and optical characterisation, and look to perform free space optical communications using the devices. "

“该项目开发了一种基于谐振隧道二极管的新型太赫兹发射器天线设计。传统系统的问题是太赫兹波被捕获在基板内，然后通过使用光子晶体结构、喇叭天线等来提取。在这个项目中我们利用 DRA 概念形成一个具有谐振的盒形腔，旨在有效提取太赫兹波。学生将通过利用谐振隧道二极管作为振荡元件的介电谐振器器件进行模拟来开发设计。将与谢菲尔德大学（DRA 设计）和日本罗姆半导体（基于制造和应用方面）的同事合作，这项工作将围绕器件制造技术（电子束光刻、干法和湿法蚀刻）的开发以及围绕 DRA 概念进行设备设计。学生将在实验室内开发电气和光学特性测试能力，并寻求使用这些设备进行自由空间光通信。 ”
