Metamaterials Analysis and Design

Metamaterials are artificially structured sub-wavelength materials that have electromagnetic properties not previously observed in nature; notably negative permittivity, negative permeability and negative refractive index. The full extent of application for metamaterials is unknown but metamaterials may find possible applications in perfect lenses, cloaking devices and in the further miniaturisation of electronic circuitry. This project numerically designed, simulated and analysed four different metamaterial structures resonant at terahertz frequencies in order to extract and demonstrate the characteristics of negative permittivity, negative magnetic permeability and negative refractive index.
