Abstract
The current study of SPP(Surface Plasma Polariton)coupling performance and propagation in this area has become the subject of much-needed improvements.In order to further enable SPP nanodevices possible,SPP waveguide structure is used to design a surface plasmon loop filter,SPP waveguide structure transmission model and metal grating SPP transmission model are established.The simulation analysis for transmittance shows that the transmittance changes with the metal film thickness varies.When the thickness of the metal film is reduced,the transmission bandwidth is significantly narrowed,and the transmission peak is also reduced.The simulation results for filter structure design show that the filter has a strong matting effect;simultaneously with an effective resonant frequency can be better achieved hinder non-resonant frequency.This research has both theoretical and practical significance for the practical application of nanoion laser and other components.
