“…The reason for such effort lies on the quite promising features of terahertz signals for imaging and sensing applications [1]- [2]. One of the major challenges in designing such structures comprises the mitigation of the high losses presented by dielectric media in the THz spectral region [3]- [4]. Regarding this aspect, some works have investigated the usefulness of some polymer compounds to structure THz waveguides [5]- [6].…”

The development of SPP-based terahertz waveguides has demonstrated being of great potential to achieve an appropriate trade-off between losses and dispersion, particularly for sensing and imaging operations at that spectral band. In this work, we implement a microstructured fiber comprising an air core surrounded by an array of silver rods and air holes. With our geometry, we can reach losses of 0.01 cm -1 and dispersion nearly zero for a broad range of the terahertz region. Our goal is to demonstrate that we can optimize those waveguide structures to improve their properties at terahertz band.
