The University of Exeter’s Centre for Metamaterial Research and Innovation (CMRI) with Dstl, is inviting applications for a fully-funded PhD studentship with enhanced stipend. For eligible students, the studentship will cover home tuition fees plus an annual tax-free stipend of at least £21,622 (UKRI rate + £3,000) for 3.5 years full-time, or pro rata for part-time study. There is also a budget to support your research project and training of at least £15,000.  The student would be based in the Department of Physics and Astronomy within the Centre for Metamaterials Research and Innovation at the Streatham Campus in Exeter.

Anticipated start: Sept 2024

Project Description

The main hurdle in advancing antenna technology is the issue of miniaturization. Traditional antenna’s function based on electromagnetic (EM) wave resonance and their size is typically larger than one tenth of the EM wavelength, λo. This restricts the potential for antenna size reduction, complicating the achievement of compact antennas and antenna arrays. This issue is especially prominent at very-high frequency (VHF, 30–300 MHz) and ultra-high frequency (UHF, 0.3–3 GHz) ranges with larger λo, severely limiting the possibilities for wireless communication systems.

In contrast, recent advancements have shown that a strong strain-mediated magnetoelectric (ME) coupling in magnetic/piezoelectric heterostructures can effectively enable energy transfer between magnetic and electric fields [Lage, E. et al. Exchange biasing of magnetoelectric composites. Nat. Mater. 11, 523–529 (2012); Bibes, M. Towards a magnetoelectric memory. Nature 7, 425–426 (2008)]. If this strong ME coupling can be dynamically achieved at radio frequencies (RF) within ME heterostructures, it may enable voltage-induced RF magnetic currents capable of radiating EM waves. Additionally, it could potentially lead to the creation of acoustically actuated ME antennas with a novel mechanism for transmitting and receiving EM waves. This concept has been recently proposed in theory [Domann, J. P. & Carman, G. P. Strain powered antennas. J. Appl. Phys. 121, 044905 (2017)].

The ME antenna operates at their acoustic resonance rather than EM resonance. Considering that the acoustic wavelength is around five orders of magnitude shorter than the EM wavelength at the same frequency, these ME antennas are likely to be of sizes like the acoustic wavelength. As such, they can be significantly smaller than current compact antennas, offering a considerable reduction in size. Creating multifunctional ME antennas involves utilizing multiferroic materials that exhibit the primary ferroic properties of ferromagnetism, ferroelectricity, and ferroelasticity. Composed of two essential thin-film components—piezoelectric and magnetostrictive materials, the ME antenna operates through a sequence of interactions between these components.

It highlights the GSG (ground-signal-ground) configuration, delineates the various material layers, provides a cross-sectional view, and depicts an individual antenna unit cell. (b) Illustrates the working principle of the ME antenna, demonstrating its functionality in both transmission and reception modes. Additionally, it outlines the specific modules that will be utilized for simulation within the COMSOL environment.

This PhD project aims to focus on the innovative development of multifunctional ME (Magneto-Electric) antennas by understanding ferroic properties, creating efficient prototypes, and evaluating potential applications. The key objectives include material analysis and selection of appropriate piezoelectric and magnetostrictive materials, development of computational models for simulating antenna behavior, creation of prototypes through design and fabrication, comprehensive laboratory testing to assess performance, and comparison of ME antennas with traditional RF antennas in terms of size reduction, multifunctionality, and other potential advantages.

About the Centre for Metamaterials Research & Innovation

You would be joining the doctoral training programme at the Centre for Metamaterial Research and Innovation (CMRI) at the University of Exeter.  We support all our students in developing their scientific knowledge whilst also providing transferable and technical skills training to prepare them for careers within and outside of academia.

The PhD students learn together in targeted courses, self-driven activity groups, and exposure to industry to gain scientific background knowledge beyond their areas of expertise, and to equip themselves with transferable professional skills such as creative thinking, project management, and leadership. We are now home to a diverse community of over 30 active PhD students (Postgraduate Researchers, PGRs) who are training in a stimulating, challenging yet supportive cohort-based environment. Since 2018, over 65 graduates have entered employment in industry and as postdocs in Higher Education Institutions in and outside of the UK.

The Award

This award provides annual funding to cover Home tuition fees and a tax-free stipend.  For students from the UK who pay Home tuition fees the award will cover the tuition fees in full, plus at least £21,622 per year tax-free stipend (UKRI rate + £3,000, increasing each year as per UKRI standard PhD stipend).  There is also a budget to support your research project and training of at least £15,000. The conditions for eligibility of home fees status are complex and you will need to seek advice if you have moved to or from the UK (or Republic of Ireland) within the past 3 years or have applied for settled status under the EU Settlement Scheme.

The studentship will be awarded on the basis of merit for 3.5 years of full-time study.
