Dielectric resonator antennas (DRA) for high power THz emitters.

“该项目开发了一种基于共振隧穿二极管的THz发射器的新型天线设计。传统的系统遭受太赫兹波被困在基板内，随后通过使用光子晶体结构，喇叭天线等提取在这个项目中，我们利用的概念，形成一个盒形腔的谐振设计，以允许有效提取的太赫兹波。学生将通过模拟利用共振隧穿二极管作为振荡元件的介质谐振器器件来开发设计。这将与来自谢菲尔德大学（设计）和日本Rohm半导体（制造和应用方面）的同事合作。这项工作将围绕着器件制造技术（电子束光刻，干和湿蚀刻）和器件设计的发展，围绕着可编程逻辑器件的概念。学生将在实验室内开发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。"

"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. "
