Hybrid Surface Plasmon Polaritons (HSPPs) in Plasma-based Elliptical Waveguides with Graphene Layers
In this article, tunable surface plasmon polaritons (SPPs) in graphene-based elliptical waveguides containing gyro-electric layers are investigated. The general structure has an elliptical cross-section, where each gyro-electric layer is surrounded b
