We discuss the scattering properties of the core–shell nanowires containing metallic core with nonlocal effects and radially anisotropic shell based on the nonlocal full-wave theory. The tunable extinction spectrum could be obtained by adjusting the anisotropy parameter and geometric size of the core–shell nanowires. The main peak resulted from transverse mode would be enhanced with the optimal anisotropy parameter. The subsidiary peaks due to the longitudinal mode become dense for the coated nanowires with thin anisotropic shell. Moreover, S-shaped and Z-shaped Fano resonances in the core–shell nanowires are presented under weak dissipation. These results will have potential applications in optical communications and ultra-sensitive detections. |
