在本文中，我们报道了一种在单线传输线上激发表面波的新颖方法的结果。虽然这些波是由Goubau在几十年前提出的，但我们结构的新奇之处在于实现了宽带平面激发。这种配置非常适合太赫兹频率范围，并允许使用包括微流控功能的新型生物微型机电系统以高空间分辨率研究生物实体。根据实验结果，我们比较了不同类型的共面波导的跃迁，也使用了不同的衬底。结果表明，对于石英衬底上的结构，这种激发方式是高效和宽带的。
In this paper, we report results on an original way to excite surface waves on a single-wire transmission line. Although these waves were proposed many decades ago by Goubau, the novelty of our structures is to achieve a broadband planar excitement. This configuration is very well suited for the terahertz; frequency range and allows the investigation of biological entities with high spatial resolution with the use of novel biomicroelectromechanical systems, which include microfluidic functions. From experimental results, we compare different types of transitions from coplanar waveguides, and different substrates are also used. We show that the excitation is highly efficient and broadband for structures on a quartz substrate.
