In contrast, for metamaterials, there are only two models: Drude model for infinitely long wires, and Lorentz model for resonant structures (e.g., short metallic wires and split-ring resonators ...

In plasmonics, the Lorentz model is superseded by the widely used Drude–Lorentz model 4, where the outer electrons of atoms are no longer bound, and move freely through the metal allowing it to ...
