ESA/NPL/Cambridge funded PhD studentship in the area of applied electromagnetic metrology with a wide range of applications (eg. space exploration and technology, wireless communications, radio cosmology, etc). The next generation radio cosmology instruments, the current and upcoming communication systems (e.g. 5G/6G), the rise of the Internet of Things and Energy Harvesting, as well as the future ultra-sensitive payloads for space exploration and space-based systems, all have something in common: the need to measure and characterise extremely low levels of electromagnetic emissions.
