THz long range plasmonic waveguide in membrane topology

In this communication, we present THz planar strip plasmonic (THz-PSP) structures based on planar Goubau lines (PGL). In order to improve different propagation characteristics, a membrane approach is studied because it is more convenient for low dispersion propagation and for a long range plasmonic behaviour. Resonating structures such as split ring resonators (SRR) along the plasmonic waveguide can be added to this structure in order to maximize the coupling between them.
