Abstract

Metamaterials are novel structures that show unique optical properties and promise applications such as perfect lenses, filters, invisibility cloaks and antennas [1, 2]. Various metamaterial structures with different metals and semi-conductors have been investigated to date [3, 4]. In this study, fishnet structures based on indium tin oxide (ITO) patterned on quartz substrates are investigated in the terahertz region. ITO thin films form an integral part of various optoelectronic devices [5]. Their use as electromagnetic filters is expected to gain importance as interest in developing terahertz range wireless data transfer architectures develops. The structure consists of a sub-micron thick ITO thin film patterned on a quartz crystal substrate. The transmission of THz radiation is analyzed with respect to the dimensions of the pattern. ITO conductivity is on the order of 100 times less than as in gold, which decreases resonant effects observed through various patterns. Using FDTD simulation, not only did we observe a diminished resonance but it was also shifted towards the low frequency THz range for as compared to the same pattern simulated as a perfect conductor. The validity of the simulations are compared to fabricated structures characterized by both our home-built terahertz time domain spectroscopy (THz-TDS) systems and continuous wave tunable THz systems.
