In a project supported by Victoria and AFAS-Vic Fellowships and the Australian Research Council, the Functional Materials and Microsystems Group have realized terahertz devices for metamaterials.
The terahertz regime covers the 0.3-3.0×1012 Hz frequency range, corresponding to 100 μm to 1 mm wavelengths.
Subwavelength structures for terahertz (e.g., λ/10) fall within the regime of micro-fabricated devices. Utilising our micro-fabrication capabilities, we have realized terahertz devices for metamaterials – with the first examples of elastomeric, flexible metamaterials and planar metamaterials for sub-diffraction thin film sensing – and the generation of surface plasmons. We have also demonstrated mechanically tunable metamaterials with high sensitivity and polarisation dependent performance.
This research project has been supported by Victoria and AFAS-Vic Fellowships and received equipment funding from the Australian Research Council (Linkage, Infrastructure, and Equipment LE150100001, 2015).
