• 論文の詳細を見る

• In this study, we focus on near-field characteristics and surface plasmon (SP) induced by uniform- and nonuniform-size Ag nanoparticles in the mask layers of super-resolution near-field structure (super-RENS). The finite-difference time-domain (FDTD) method is used to analyze scattering fields from the localized SPs of Ag nanoparticles. It has been found that the spatial extension of the evanescent field is very short along the thickness direction of the mask layers, and the three-dimensional coupling patterns of the evanescent fields from the nonuniform-size particles are the most irregular. The signal enhancement mechanism of a super-RENS disk is discussed.
