Abstract
A novel compact slow wave structure (SWS) based on spoof plasmonic waveguide with meander lines in the terahertz (THz) and microwave frequency range is proposed. The use of the meander lines increases the effective length of the proposed structure thereby providing more path length for efficient trapping of the spoof surface plasmon polaritrons (SPPs). The meander line based SPPs structure is designed in THz and microwave frequency range using the full wave electromagnetic field simulator, the CST Studio. The area of proposed SWS is found to be reduced by 75% as compared to that of the conventional rectangular based surface plasmonic waveguide structure. The experimental verification of the proposed SWS is carried out in the microwave frequency band by fabricating the scaled up version, and measuring the transmission coefficient data using the network analyzer.
