This PhD project will investigate the design and manufacturing of superconducting devices for radio astronomy, exploring the relationship between different fabrication processes' limitations, device geometry and microwave performance.
The initial work will establish the capabilities and limitations of laser scribing for these devices, using single inductive devices and resonators. Subsequent research will extend on these findings to pursue related designs in kinetic-inductance travelling-wave parametric amplifiers (KITWPAs) for low-noise receiver systems, as well as manifold multiplexers for spectroscopy using highly selective, high-order microwave networks.
The project brings together electromagnetic modelling, microwave circuit design, device fabrication and experimental characterisation, with applications in astronomical instrumentation and quantum computing.
Research environment
You will join the University of Pretoria’s microwave and microelectronics research team at the Carl and Emily Fuchs Institute for Microelectronics (CEFIM), which hosts a range of enabling facilities to support this project. These include appropriate simulation and modeling software, laser-based planar prototyping, wafer probing, and RF and millimetre-wave measurement capabilities extending to 220 GHz. Cryogenic testing will be completed with appropriate partner institutions in Cape Town and Germany.
Candidate profile
Applicants should hold a master’s degree in Electronic Engineering, Physics, or a closely related field, with a strong background in one or more of:
- Electromagnetics
- Radiofrequency and microwave circuits
- Astronomical instrumentation
Applicants currently completing their master’s degree may apply, provided that they complete the qualification before commencing the PhD.
