Evolution from air-cladded to effective-medium-cladded dielectric waveguides
2019 44th International Conference on Infrared, Millimeter, and …, 2019•ieeexplore.ieee.org
Integrated guiding structures with low loss, low dispersion and broad bandwidth are
demanded in high-performance terahertz systems. In this work, an effective-medium-
cladded waveguide fabricated on a single high-resistivity silicon wafer is proposed for
terahertz operation. The effective medium is realized by regularly perforating a silicon slab
with a period in the subwavelength region. The simulated average attenuation coefficient is
around 0.05 dB/cm over the operation frequency range from 220 GHz to 330 GHz for the E …
