电磁环境测量博士职位

The rapid electrification and digitalisation of society are creating increasingly complex electromagnetic environments. Fast-switching power electronics in vehicles, buildings, hospitals and farms can generate electromagnetic interference (EMI) that propagates through unexpected conducted and radiated paths. Conventional EMC measurements, typically performed at a single location and moment, provide only limited insight into how such interference behaves at system level.

In this PhD project, you will develop the measurement and analysis methods needed to make these environments observable. You will design and validate a cost-effective, synchronised multi-node sensing system for simultaneous time-domain measurements of voltages, currents, electric fields and magnetic fields, supported by digital signal processing.

Using these synchronised measurements, you will develop methods to correlate information across time, frequency, space and impedance. The aim is to identify interference sources and propagation paths and understand how disturbances spread through complex electrical systems. This work will provide an important foundation for future cognitive EMC systems that can ultimately adapt mitigation measures to changing conditions.

A key application will be dairy farms , where increasing electrification and automation can give rise to stray currents and voltages that are difficult to locate and may affect cow welfare and behaviour . You will perform measurements on farms to determine where these disturbances originate and how they propagate, and use this understanding to investigate practical mitigation, including targeted filtering solutions. In this way, your research can contribute directly to solving a real problem experienced by farmers while advancing the state of the art in EMC.
