The results indicate that the nonlocal EMT is the simplest and most accurate approach to describe the characteristics of plasmon-polaritons at the epsilon-near-zero regime (e ≈ 0) in the polaritonic metamaterial. In contrast, the Maxwell-Garnett effective medium approximation is considered to be the most general method to study the generated plasmon-polaritons in metamaterials. An additional plasmon-polariton is found in the polaritonic metamaterial through the nonlocal EMT, which could not be found with the Maxwell-Garnett EMT. A flat longitudinal wave-number of the excited plasmon-polariton occurs in the angle of incident light ranging from –20 to 20°, leading to the collinear group-velocity vectors, and its energy will be carried in one direction. The findings can be used in some applications in optical communication.</p>}, number={1B}, journal={Hue University Journal of Science: Natural Science}, author={Anh, Nguyen Pham Quynh}, year={2021}, month={Oct.}, pages={35-41} }
