Abstract :
We report in this communication 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 structure is to achieve a planar excitement. This configuration is very well suited for the terahertz frequency range and allows the investigation of biological entities with micrometer spatial resolution.
