PhD Vacancies
- Photonically Controlled Microwave Circuits and Antennas
PhD applications are sought for funding opportunities in the area of photonically controlled microwave circuits and antennas. This exciting and versatile new technology uses light to produce rapidly reconfigurable conducting surfaces at low cost. The work is sponsored by L-3 TRL (www.trltech.co.uk) a leading UK based technology company.
Applications are sought from UK citizens or EU citizens with at least a 2.1 degree from a UK university. If successful you will be based in the Photonics Research Group in Electrical and Electronic Engineering at the University of Bristol. This is one of the leading Photonics research groups in the UK with excellent facilities in both the photonics and microwave photonics areas. Experience in optoelectronics, microwave electronics or electromagnetics is preferred, but not essential.
