Research Groups

The Department is actively engaged in research and development of advanced information, electronics, communications and computer systems. Major areas of research include applied nonlinear circuits and systems, complex systems and networks, multimedia signal processing, optical communication, power electronics, telecommunications, and thin film and optoelectronics. Results from research in these areas are either of academic value or are readily translated into marketable industrial applications.

 

Applied Nonlinear Circuits and Systems Research Group

The Applied Nonlinear Circuits and Systems Research Group's main research interests include power electronics, complex networks, nonlinear dynamics, chaos communications and time-series analysis.

• Leader: Prof. C.K. Tse
• Members:
  Dr Martin Chow, Dr Y.M. Lai, Dr Francis Lau, Dr Michael Small, Dr S.C. Wong
  (Historical Note on Membership: In August 2004, the former power electronics group was ungrouped as a result of retirement and departure of a number of its group members. As an interim arrangement, the Applied Nonlinear Circuits and Systems Group has integrated with the former power electronics group, covering a slightly wider research interest.)
