Abstract

We investigate surface plasmon waves propagating on planar Goubau lines, so-called Goubau mode, using a guided-wave terahertz spectroscopy system based on a freely positionable electro-optic probe. We show the radial nature of the Goubau mode and its confinement around the Goubau line over few tenths of microns (lamda/10).
