Summary:This abstract presents a complete study of dispersion and mode distribution of spoof surface plasmons (SSPs) in planar metal gratings. The subject under investigation is intended for Terahertz wave generation. Because of its characteristics of near field localization of this plasmonic wave and collective resonance effects of electrons in metals, SSPs in this textured metal surface has attracted enormous interest such as potential applications in plasmonic metamaterials (F. J. García-Vidal. et al., J. Opt. A: Pure Appl. Opt, 7, 2005, S97-S101). There are many novel phenomena steam from surface plasmons, such as enhanced total reflection (G. A. Plotz. et al., J. Opt. Soc. Am., 69, 1979, pp.419-422), extraordinary optical transmission (T. W. Ebbesen. et al., Nature, 391, 1998, pp. 667-669), enhanced Raman spectroscopy (P. L. Stiles. et al., Ann. Rev. Chem. 1, 2008, pp. 601-626), superradiant Terahertz Smith-Purcell radiation (Y. M. Shin. et al., Appl. Phys. Lett. 90, 2007, pp. 031502), etc.
