The project will explore liquid crystals and organic thin films and their use for THz beam manipulation, exploring their strong interaction with artificially micro- and nano-structured surfaces (metasurfaces). The metasurfaces will be designed, fabricated in the cleanroom and then characterised experimentally to measure the localised enhancement of the electric field and the spatially dependant material parameters. This project also involves modelling to study the underlying physics of strong light-matter interaction. Theis multidisciplinary PhD research offers a good balance of fundamental and applied science, uniting the two in order to take forward our groups' successful research in THz photonics and liquid crystal devices.

该项目将探索液晶和有机薄膜及其用于THz光束操纵，探索它们与人工微纳米结构表面（元表面）的强烈相互作用。超颖表面将被设计，在洁净室中制造，然后通过实验来测量电场的局部增强和空间相关的材料参数。该项目还涉及建模，以研究强光物质相互作用的基本物理学。Theis多学科博士研究提供了基础科学和应用科学的良好平衡，将两者结合起来，以推进我们小组在太赫兹光子学和液晶器件方面的成功研究。
