Embodiment Construction
[0024] Embodiments of the invention are described in detail below, examples of which are illustrated in the accompanying drawings. The embodiments described below by referring to the figures are exemplary only for explaining the present invention and should not be construed as limiting the present invention.
[0025] Some recent research work revealed that Effective Localized Surface Plasmon Polaritons (Effective Localized Surface Plasmon Polaritons, ELSPs) can more effectively simulate real LSPs in the optical frequency band at low frequencies. By adding periodic metal wires on the side of the dielectric cylinder, the interface between the dielectric cylinder and the air can support the LSPs mode similar to that produced by metals in the optical frequency band under the irradiation of light waves, so that the excellent height field localization characteristics and multi-pole resonance characteristics of LSPs can be realized. It can be extended to microwave and terahertz frequ...
