In order to cope with the "THz Gap", metamaterial based devices operating at about 1THz have been designed to have a tunable response. We studied the electromagnetic behaviour of periodic structures consisting of different "unit cells" based on the concept of Split Ring Resonator (SRR). The devices response in the required frequency region is simulated using a commercial electromagnetic code. Different modulation mechanisms have been investigated, including the use of liquid crystals, MEMS, semiconducting substrates. © 2011 Springer Science+Business Media B.V.

Abstract
In order to cope with the "THz Gap", metamaterial based devices operating at about 1THz have been designed to have a tunable response. We studied the electromagnetic behaviour of periodic structures consisting of different "unit cells" based on the concept of Split Ring Resonator (SRR). The devices response in the required frequency region is simulated using a commercial electromagnetic code. Different modulation mechanisms have been investigated, including the use of liquid crystals, MEMS, semiconducting substrates. © 2011 Springer Science+Business Media B.V.File in questo prodotto:
