Applied electromagnetics and devices


Dr John Dawson


This research focuses on hardware and associated physics, especially as relates to applied electromagnetics and microwave and optical devices. This includes measurement and simulation techniques for electromagnetic compatibility, and the investigation and development of shielding and other immunity and emissions control techniques.

We also investigate the effects and applications of electromagnetics on the human body, in particular for medical applications.

Linking with the group’s wireless communications research we also work on antenna modelling and design microwave circuits, filters and oscillators, along with high speed optical devices.
