Dielectric Metamaterials in the THz range

Abstract: After a short introduction to metamaterials, I will describe the last achievements obtained in cooperation between of the groups of Prague and Bordeaux (LOMA). I will focus on high-permittivity structures where the magnetic effective response is due to Mie resonances.

Thanks to an original experimental approach, we are able to simultaneously measure the complex transmittance and reflectance of a thin layer consisting of TiO2 microspheres. Thus its complex permittivity and permeability can be retrieved. Experimental results are in good agreement with simulations. The latter prove that a negative permeability of the metamaterial can be achieved by optimization of structure parameters.

I will also talk about our further commune projects where we aim to tune the resonant response of metamaterials by means of an electric field.
