| Summary: | 碩士 === 健行科技大學 === 電子工程系碩士班 === 103 === Surface plasmoneffectsin a three-dimensional silver-shellnanospherical pair with five different dielectric holes (DHs)thatinteractwithatransverse magnetic mode incident plane wave are investigatedby using the finite-elementmethod.The proposed structure exhibits a redshifted localized surface plasmon that can be tunedover an extended wavelength range by varying the dielectric constant and the radii in DHs, which cannot be found in the counterpart of solid silver nanospherical pair. The increase in the near-field intensity is attributed to a larger effectivesize of DH that is filled with a higher refractive index medium.
