Microfabrication of metamaterials

Research Area: Physics, microfabrication, interfacial science

Supervisors: Dr Rossen Sedev, Dr Jason Connor, Dr Bruce Wedding (Electrical and Information Engineering) and Laureate Prof John Ralston

Description: Metamaterials exhibit unusual electromagnetic properties such as a negative refractive index. There has been much excitement in recent years about the possible applications e.g. smaller, more effective antennas; sub diffraction focusing and optics; beam steering and wave guides. Their peculiar properties arise from the structure rather than the composition of the materials. There is intense interest in developing metamaterials through microfabrication.

The project is to replicate an assembly of elements that have demonstrated such properties using state of the art microfabrication facilities at The Wark. By scaling down the structure using this approach we aim to develop a material capable of operating at shorter wavelengths. A suitable microstructure will have to be identified, engineered and tested.
