Pathonic bandcap technology
Photonic bandgap materials are one of the most rapidly advancing sectors in the electromagnetic arena. They allow engineering control over the propagation of electromagnetic waves to an extent that was previously not possible. The synergetic interaction between theory and experiment, together with substantial technological potential, has driven rapid development of photonic bandgap technology. Emphasis is now placed on finding tangible applications combined with detailed modelling. Owing to the tremendous potential of photonic bandgap (PBG) structures, there is a plethora of applications in which they can be used. These include using PBG in handset antenna designs to enable radiation to be reduced, and sub-millimetre wave antennas.
