Material Characterization of Liquid Crystals at THz-Frequencies using a Free Space Measurement Setup.

Kurzbeschreibung (Abstract)
Liquid crystals (LCs) are promising materials for passive tunable components at microwave frequencies and optics. With increasing interest in the THz frequency domain the quest on tunable THz components rises. For the systematic design of such tunable components like phase shifters or reflect arrays a detailed knowledge of the dielectric material properties at the intended frequency is needed. In this paper we show measurement results for the characterization of two commercial LCs (K15 and E7, both from Merck) at frequencies between 100 and 350 GHz performed with a free space CW THz system. An anisotropy of DeltanK15 = 0, 05 and DeltanE7 = 0, 08, respectively, could be determined in this frequency range.
