N2  - Surface plasmons are an important part of the arising field of nanophotonics which explores the confinement of electromagnetic fields on subwavelength scale. They can take various forms, ranging from freely propagating electron density waves along metal surfaces to localized electron oscillations on metal nanoparticles. The promising properties of Surface plasmons come from the interaction between the free electrons oscillations and electromagnetic waves of light. One of the most interesting properties of using Surface plasmons is their capability of light confinement and propagation using subwavelength structures. This could help to minimize photonic devices with scales less than those recently accomplished. In this regards, numerical simulations can be used to characterize and design of plasmonic devices. In this dissertation, a novel asymmetric channel plasmon polaritons (CPPs) is proposed and analyzed. The dispersion characteristics of asymmetric two and three-trenched CPPs structures are studied in detail. The suggested asymmetric structures have advantages in terms of propagation length and figure of merit over the symmetric CPP waveguides. In addition, a comparative study of various CPP metals including Gold and Silver is also presented. It is found that the propagation length and figure of merit of the Silver-based structures are better than those of Gold-based structures. In addition, the effect of bending on the asymmetric CPP waveguides is investigated. The simulation results are obtained by full-vectorial finite difference method (FV-FDM) with irregular meshing capabilities and perfectly matched layer boundary conditions
