The Electrical and Electronic Engineering Research Group seeks to advance fundamental knowledge and promote applications across the whole spectrum of activities in topics relating to electrical and electronics. This spans the development of new semiconductor devices and laser components for applications such as holographic cameras to techniques for high power DC transmission; novel circuit design; design of algorithms for sensor networks with applications ranging from subsea to solar-power video monitoring of the natural environment; and the engineering of new Internet transport mechanisms.

Work on transmission technology has one focus on broadcast TV. Recent years have seen a change from delivery as Internet over existing communications infrastructures to delivery of communication service over Internet infrastructure. These changes have impacted the way mobile networks are designed and operated. Similar changes are imminent for TV broadcast networks. World-leading research in Aberdeen is currently playing a key role in setting new standards for a converged broadcast/Internet. Other areas of active research include sensor networks for remote observation and techniques for subsea communications to support the oil and gas industry.

The Internet Engineering group focusses on new transport technologies for the modern Internet to update the way the network is used to support a wide range of applications, from streaming media, Internet TV, VoIP, to the most recent updates to web technologies. The diversity of use and the wide range of network characteristics make this a challenging topic for Internet engineers. Work in Aberdeen focusses on transport for multimedia, evolution of TCP and network protocol design at the transport layer where it contributes to the work of the Internet Engineering Task Force (IETF,

The power group conducts leading research in the design and analysis of power systems and power electronics. This includes power electronics applications to transmission systems such as HVDC (High Voltage DC Transmission) and FACTS (Flexible AC Transmission Systems), with projects developing new technologies for high power DC transformers, DC circuit breakers and DC transmission networks.

Activities by members of the research group include many inter-related and multi-disciplinary topics including:

  • Development of novel low-cost high-frequency band-gap semiconductor devices for imaging

  • Design, layout and simulation of electronics systems

  • Development of new laser systems for medical and biological applications

  • Internet engineering of network transport protocols to support web-based conferencing

  • New techniques for satellite broadband to support deployment to rural communities

  • Video compression for challenging Internet paths

  • High voltage dc transmission for next generation distribution grids

  • Holographic imaging processing and subsea holographic camera development

  • Standards for broadcast of TV and data using Internet techniques

The group is an active participant in the European Satellite Network of Experts (SatNEx, designed to achieve long-lasting integration of key European satellite communications research centres. Our participation in the recently funded £11.8 M RCUK Digital Hub supports cross-disciplinary applied research to develop digital technology that will transform the lives of people in rural communities.
