Abstract:	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 E₁₁× mode.
