Study of SPP Mode of Isotropic Plasma Filled Graphene Circular Waveguide
摘要
The study of SPP (surface plasmon polaritons) mode of isotropic plasma filled graphene circular waveguide was investigated theoretically. The main focus and interest of this study are used isotropic plasma. The characteristics of plasmon modes could be tuned by changing nanowire radius. The dispersion relations are derived. The modal behaviors can be effectively tuned by changing the plasma frequency, collision frequency, and radius of the isotropic plasma. The results demonstrate that the behavior of the different plasmon modes in magnitude and orientation is highly affected by the collision and the plasma frequency on different modes.
