"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. "

这个项目开发了一种基于共振隧道二极管的新型太赫兹发射器天线设计。传统系统的缺陷是太赫兹波被困在衬底中，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的概念来形成一个带有共振的箱形空腔，旨在允许有效地提取太赫兹波。学生将通过模拟使用共振隧穿二极管作为振荡元件的介质谐振器设备来开发设计。这将与谢菲尔德大学(DRA设计)和日本罗姆半导体(基于制造和应用的方面)的同事合作。这项工作将围绕DRA概念开发器件制造技术(电子束光刻、干法和湿法蚀刻)和器件设计。学生将在实验室内发展电气和光学特性的测试能力，并希望使用这些设备进行自由空间光通信。“
