Investigating Electromagnetic Surface Waves in Nonlinear Metamaterial Waveguide Structures Near the Dirac Point

Khitam Elwasife

Abstract: This study theoretically examines electromagnetic surface waves in a nonlinear dielectric film bounded by a ferrite cover and negative zero positive index metamaterial substrate. The results, expressed in terms of the systems physical parameters, reveal that the proposed waveguide structures refractive index can be efficiently controlled by tuning the operating frequency. This research contributes to our understanding of surface waveguides and their potential applications in guided wave optics and integral optics.
