Abstract :
Spoof surface plasmon polariton (SSPP) based devices have recently garnered a great deal of attention owing to their ability to propagate THz signal without dispersion and very low signal attenuation. In this paper, a rigorous mathematical model has been proposed by performing full-field analysis on the periodically corrugated cylindrical waveguide. It has been shown that this structure has the capability of propagating localized spoof surface plasmons polariton (SSPP) mode of EM waves. The variation of band diagrams as a function of different groove dimensions has been investigated. Finally, by employing cylindrical SSPP a new polarizer controller has been designed that can be utilized to design THz Boolean gates.
