Time-domain characterization of Terahertz surface scattering and inhomogeneous media for communication and remote sensing

Project Description

The frequency range between 0.1 and 3 THz holds promise for a myriad of applications such as high-speed communication and remote sensing. Hence, a great deal of effort has been carried out in recent times toward the development of the components and systems operating in such frequency range [1]. However, even with state-of-the-art THz devices any foreseen application will struggle to deliver the expected impact due to the lack of channel characterization at those frequencies. This PhD research programme will focus on the characterization of Terahertz scattering from random (rough) surfaces, frequency selective surface (metasurface) wallpapers, and of inhomogeneous media. Knowledge of surface properties and propagation media at a length scale corresponding to sub-millimetre wavelengths is fairly limited [2]-[4] and both experimental characterisation and modelling are required enable the construction of suitable channel models. In particular the PhD student will carry out (i) experimental work using mainly an all fibre-coupled Terahertz time-domain spectrometer; a PNA network analyser may be used when required; and (ii) development of models for Terahertz surface scattering. Other activities supporting the study will also be carried out when required. We expect the PhD candidate to develop the expertise required to lead an experimental research project, to train students, to interact with colleagues with different backgrounds (physics and engineering) and from different disciplines (i.e., electromagnetism, radio-propagation, material science). Details of the project will be agreed with the interested candidates to tailor the research to his/her interests. The research programme will take place in an international and interdisciplinary environment, which will substantially favour collaboration opportunities 1) within the School of Physics and Astronomy, 2) within the School of Engineering, and 3) within other research institutions.

Funding Notes

Applications are sought from highly motivated students graduating with first degree (2:1 or higher) in physics or engineering (and preferably a Master degree). Funding is awarded by the School on a competitive basis, depending on the strength of the applicant. The funding is only available to UK/EU nationals, and it will cover tuition fees and provide a stipend for 3.5 years. Non-EU Students: If you have the correct qualifications and access to your own funding, either from your home country or your own finances, your application to work on this project will be considered.
