We have a broad range of research centred on the applications of microwave technology into communications and sensor systems, and on novel aspects of network design with research funding from the EU, research councils, MoD and industry. We have a long tradition of excellence in electromagnetics and its applications, with exciting growth areas in microwave systems and networks.
The Antennas and Applied Electromagnetics Laboratory has world-leading work on antennas and propagation for body-centric communications and antennas for vehicles. It has extensive facilities, including two 12m2 microwave anechoic chambers, a millimetric anechoic chamber, a microwave reverberation chamber, network and spectrum analysers up to 110GHz, access to a 70m2 class 10,000 clean room, and a large suite of commercial software for simulation of microwave structures.
The MCI Laboratory is specialised in microwave active circuits and antennas and in the application of computational intelligence to control and adapt them. Facilities include a digitally modulated signal generator and vector signal analyser for the analysis of signal integrity in linearised transmitters and active antennas, interfaced to a PC for 'hardware in the loop' development of control algorithms.
The Microwave Integrated System Laboratory is active in emerging radar technology for remote sensing. In addition to the electrical engineering microwave facilities it has a 40-metre long flight imitator, unique for UK universities, positioned on the building roof, which can carry a 50kg payload.
The Networks Laboratory is engaged in the modelling of large-scale complex networks and is actively developing novel adaptive routing and MAC protocols for wired and wireless networks. It has a range of computationally intensive workstations, a wireless networking testbed and is currently setting up a wired network simulator.
Work in the optics area includes: analysis and modelling of novel optical devices such as optical amplifiers, optical filters, optical transmitters and optical receivers; generation of new codes for optical code-division multiple access (OCDMA) to minimise the multi-user interference and analysis of soliton propagation in optical fibre communications.
