"The current project aims to investigate metamaterials acting as tunable frequency filters or switches working at extremely high frequencies (hundreds of GHz to units of THz). Such quasioptical devices will be created by inserting defects into a periodic arrangement of dielectric materials exhibiting a forbidden band of photon energies. It is necessary to choose defects with optical properties depending on an external parameters; this leads to tunability of the pass band which is important for expected applications. This kind of structures will be designed, studied theoretically by means of a computer model, set up and studied experimentally by means of time-resolved terahertz spectroscopy with phase sensitivity. The project is expected to contribute to the development of information and communication technologies in the region of tenths to tens of THz."@en .
