Microwave Antennas and Waveguides in Photonic Crystals. We propose to design a revolutionary new class of microwave antennas and antenna arrays in photonic crystals, which can shield, localise and guide electromagnetic radiation in a dielectric environment. This design is completely devoid of metal, thereby eliminating skin-effect losses that are the dominant limitation for planar antenna arrays at upper microwave (millimetre-wave) frequencies.

We propose to design a revolutionary new class of microwave antennas and antenna arrays in photonic crystals, which can shield, localise and guide electromagnetic radiation in a dielectric environment. This design is completely devoid of metal, thereby eliminating skin-effect losses that are the dominant limitation for planar antenna arrays at upper microwave (millimetre-wave) frequencies. Our new design will achieve high radiation efficiencies and antenna gains not possible with existing planar technology, thereby enabling new applications of planar antenna arrays, for example to radio astronomy, as well as greatly improving existing applications.Read moreRead less
Topologically nontrivial electromagnetic states. Topological properties play a fundamental role in many physical phenomena. The best known examples are quantum Hall systems, where insensitivity to local properties manifests itself as conductance through edge states that is insensitive to disorder. While the traditional research focus has been on electronic systems, there has been a recent emergence of great interest in exploring topological orders with photons. Several novel intriguing theoretic ....Topologically nontrivial electromagnetic states. Topological properties play a fundamental role in many physical phenomena. The best known examples are quantum Hall systems, where insensitivity to local properties manifests itself as conductance through edge states that is insensitive to disorder. While the traditional research focus has been on electronic systems, there has been a recent emergence of great interest in exploring topological orders with photons. Several novel intriguing theoretical schemes have been proposed to explore topological orders in photonic systems, both in the linear and strongly interacting regimes. This project aims to develop innovative theoretical and experimental approaches to explore topologically non-trivial states, from microwaves to optical regimes.Read moreRead less
New regularisation techniques in electromagnetic diffraction from cavities and related complex scatterers. Modern technology, such as radar and other imaging devices, exploits the information carried by electromagnetic waves. New technology depends centrally upon advances in the mathematics of waves to give precise, reliable and effective means of predicting how objects capture and re-radiate wave energy in the scattering environment.

Modern technology, such as radar and other imaging devices, exploits the information carried by electromagnetic waves. New technology depends centrally upon advances in the mathematics of waves to give precise, reliable and effective means of predicting how objects capture and re-radiate wave energy in the scattering environment. This project aims to develop a new mathematical approach to wave scattering by objects with complex scattering mechanisms, as typified by cavity structures. This new formulation is obtained by a process of analytical regularisation of the equations describing the scattering process. It generates algorithms more reliable and computationally accurate than current codes.
