Postdoctoral Position in THz Plasmonics (Univeristy of Bath and Imperial College)
A 2 year postdoctoral position under the supervision of Steve Andrews (University of Bath) and Stefan Maier (Imperial College) in plasmonics and metamaterials at THz frequencies is available. The project entails the development of a new generation of THz near-field optical components using plasmonic radiation-guiding structures such as our recently described planar metamaterials (APL 88, 251120, 2006) and metawires (PRL 97, 176805, 2006). Metawires are periodically corrugated metallic wires and tapers, exhibiting spoof surface plasmon polaritons which could allow the superfocusing of THz radiation into deep sub-wavelength volumes (see figure). Potential applications are high dynamic range near field THz microscopy, spectroscopy and biosensing.
We are looking for a highly motivated experimental scientist with experience of one or more of the following areas: THz or ultrafast techniques, plasmonics and microfabrication. The individual will have the opportunity to work with an existing state-of-the-art THz time-domain spectroscopy system, based on freely positionable, photoconductive transmitters and receivers pumped via hollow-core photonic crystal fibres and to adapt it for near field probing. Although most of the project will entail experimental work, including using a nano-fabrication facility in the department (www.bath.ac.uk/physics/cleanroom/), there will also be the opportunity to become involved in the computer modelling side of the program and to interact with our theoretical collaborators in Spain (Francisco GarcÃÂa-Vidal and Luis MartÃÂn-Moreno).
The post will be based in Bath and is offered on a competitive salary for an initial term of 2 years, with a start date in January 2008 or as soon as possible thereafter.
Potential applicants should contact either Steve Andrews (S.R.Andrews@bath.ac.uk) or Stefan Maier (S.Maier@imperial.ac.uk) or for further details.
Deadline: Nov 30th 2007
