Metamaterials are artificially designed media that show averaged properties not yet encountered in nature. Among such properties, the possibility of obtaining optical magnetism and negative refraction are the ones mainly exploited but epsilon-near-zero and sub-unitary refraction index are also parameters that can be obtained. Such behaviour enables unprecedented applications.
Within this work, we will present various aspects of metamaterials research field that we deal with at our department. From the modelling part, various approaches for determining the value of the refractive index, permittivity and permeability can be used and we will present the ones developed and used at our group. Also, using transformation optics approach, one can determine the needed values for the permittivity and permeability in order to obtain the needed functionality. Approaches in this area will be presented.
From the fabrication point of view, various 2D and 3D high resolution patterning techniques are used. The talk will describe the ones available within our group, starting with the classic UV-lithography and ending with more advanced ones, e.g. 2-photon-polymerisation and electron-beam lithography.
Measuring possibilities, both in the VIS/IR and well as in the THz regime, used for characterising the samples will be presented. The experimental challenges will be tackled during the talk.
