True Time Delay Gradient Metasurfaces for Terahertz Pulse Waves
Applications are now CLOSED
Overview
Terahertz (THz) pulse waves are transient electromagnetic radiation with duration timescale in the picosecond. They exhibit unique properties not found elsewhere in the electromagnetic spectrum, enabling new scientific and industrial applications such as spectroscopy, biomedical imaging, communications, security screening, and non-destructive testing. Currently there is no effective technique for spatio-temporal manipulation of THz pulses. Disruptive advances in this domain will lead to more efficient, cost-effective, and versatile THz systems. Pulse manipulation may involve delay, modification of its temporal shape or polarization, altering its propagation path, or focusing it at a specific point.
The aim of this project is to introduce true time delay (TTD) gradient metasurfaces, a new class of engineered structures, capable of manipulating THz pulse wavefronts concurrently in space and time. This will be achieved through theoretical analysis, simulations, and experimental demonstrations in the THz range. We will use such a structure for some use case scenarios in THz imaging or communication.
Objectives
• Developing theoretical framework for true time delay (TTD) gradient surfaces
• Developing design guide for TTD gradient metasurface
• Design, fabrication and test of the whole meta-surface
• Conducting tests on the fabricated metasurface devices for a use case scenario in THz imaging or communications
Funding Information
To be eligible for consideration for a Home DfE or EPSRC Studentship (covering tuition fees and maintenance stipend of approx. £19,237 per annum), a candidate must satisfy all the eligibility criteria based on nationality, residency and academic qualifications.
To be classed as a Home student, candidates must meet the following criteria and the associated residency requirements:
• Be a UK National,
or • Have settled status,
or • Have pre-settled status,
or • Have indefinite leave to remain or enter the UK.
Candidates from ROI may also qualify for Home student funding.
Previous PhD study MAY make you ineligible to be considered for funding.
Please note that other terms and conditions also apply.
Please note that any available PhD studentships will be allocated on a competitive basis across a number of projects currently being advertised by the School.
A small number of international awards will be available for allocation across the School. An international award is not guaranteed to be available for this project, and competition across the School for these awards will be highly competitive.
Academic Requirements:
The minimum academic requirement for admission is normally an Upper Second Class Honours degree from a UK or ROI Higher Education provider in a relevant discipline, or an equivalent qualification acceptable to the University.
