摘要

由高介电常数材料(如蓝宝石、砷化镓或硅)制成的介质杆波导(DRW)在过去已被证明具有低传输损耗和与毫米波长矩形金属波导的良好匹配。此外,还演示了各种无源元件。最近,一个单一的DRW天线已经被证明可以很好地工作在几个矩形波导波段,甚至高达1thz。此外,首次尝试将光混频器与DRW波导集成,以产生有效的太赫兹源。

Dielectric rod waveguide as an enabling technology for THz frequencies
A dielectric rod waveguide (DRW) made of high-dielectric-constant material such as sapphire, GaAs or Si has in the past been shown to have low transmission loss and good matching with a rectangular metal waveguide at millimetre wavelengths. Also various passive components have been demonstrated. Recently, it has been demonstrated that a single DRW antenna works well over several rectangular waveguide bands even up to 1 THz. Also first attempts have been made to integrate a photo mixer with a DRW waveguide to produce an effective THz source.
