Corrugated Goubau lines to slow down and confine THz waves

Résumé

Corrugations on planar Goubau lines are presented in order to slow down and focus electromagnetic waves. A propagation effective index shift is observed between corrugated and non-corrugated planar Goubau lines. Influence of the corrugation geometrical parameters is studied. Two original methods based on Bianco-Parodi differential measurements or on THz interferometer structure are validated. Finally, the effect of corrugating lines on unwanted substrate modes reject is discussed with experimental and parametric simulation studies. The wave stronger “attachment” in corrugated configurations is demonstrated.
