| Research Abstract |
The silver split-ring structure of about 100 nm in diameter was made on the glass substrate by the nano-sphere lithography method, and the scattered light spectrum from an isolated structure was observed. The feature of the mode caused in the silver split-ring resonator was clarified from the electromagnetic field enhancement calculation result by the FDTD method. Moreover, it was clarified that the origin of the scattered light peak on the long-wavelength side was LC resonance. In addition, a small silver split-ring structure was made, and the LC resonant wavelength was shortened up to 730 nm of the visible wave length region.
