This paper demonstrates a method for enhancing the performance of recently introduced compact bandpass filters for terahertz surface waves on single wire waveguides, the so-called planar Goubau lines (PGLs). It is firstly shown numerically and validated experimentally that a gapped PGL loaded with a pair of split ring resonators (SRRs) acts as a bandpass(More)
For terahertz microscopy, we propose an original approach with Planar Goubau Lines (PGL) by taking advantage of the confinement around the metallic strip. The idea is to obtain an alternative to the illumination by free space wave. The structure is fabricated on a thin high resistivity silicon substrate and it is composed of two CPW-PGL transitions, two(More)
