Tunable Terahertz Response of Split Ring Resonator Loaded Along Planar Goubau Line

In this communication, a computational and experimental investigation at terahertz frequencies of Planar Gaubau Line combined with Split Ring Resonator is reported. Different parameters such as gap width, position and gap orientation that tuned the resonance peak are studied. The obtained results are useful for the understanding of coupling mechanism between a radially polarized wave along a metallic strip and a Split Ring Resonator.
