Abstract

The optical properties of the Au/Al2O3/Ag plasmonic metawaveguide with serial periodic stub resonators were numerically investigated. The refractive index of this design provides large value by using the ultra thin Al2O3 layer. Therefore, the dispersion relation which has negative group velocity, which is similar to the case of photonic crystals, can be formed in the sub diffraction energy range. The calculation results show the dependences of the negative group velocity dispersion curves on the size of the unit cell and the stub resonators. In addition, effective material properties are presented. From these analyses, it is found that this type of design has the property to strongly modulate the propagating characteristics of light.
