Generation of plasmon-polaritons in epsilon-near-zero polaritonic metamaterial
In this paper, we study the generation of plasmon-polaritons in the epsilon-near-zero nanorod polaritonic metamaterial by using nonlocal effective medium approximation (EMT). The results indicate that the nonlocal EMT is the simplest and most accurate approach to describe the characteristics of pla...
