We report in this communication results on an original way to excite surface wave on a single wire transmission line. Although these waves have been proposed many decades ago by G. 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 BioMEMS which include microfluidic functions. We compare from experimental results different kind of transition from Coplanar Waveguides (CPW) and different substrates are also used. We show that the excitation is highly efficient and broadband for structures on quartz substrate.
