First, we want to measure the electric and magnetic near fields of a subset of meta-atoms, namely structures which are chiral and can be used for polarization control. Chirality is the last missing property in our tool box of THz meta-atoms and with that we should then be able to compose THz materials with a large variety of dielectric tensor properties. Second, we want to investigate homogeneous meta-materials with highly complex unit cells. The scientific driver behind this is to explore new avenues to generate arbitrary THz waveforms through tailored material dispersion and to apply these waveforms for THz coherent control experiments, here, of meta-materials. Third, we want to investigate inhomogeneous meta-materials, first in two-dimensional and later in three-dimensional arrays. Such materials can be used for beam steering, imaging applications, or more complex THz wave vector manipulations. Fourth, we would like to continue our efforts to reconstruct three-dimensional objects with complex dielectric constants through a suitable processing of a set of four near-field measurements and use this method in combination with all other developed previously to study THz radiation transport through media composed of oriented or random meta-atoms in general.
