発明の名称 (英語) METAMATERIAL STRUCTURE AND REFRACTIVE INDEX SENSOR NEW
発明の概要(英語) [Problem] To provide a metamaterial structure and a refractive index sensor with which it is possible to perform precise measurement inexpensively.
[Solution] A metamaterial structure 11 includes a microstructure 11a on the same level as the wavelength of incident light or less than or equal to the wavelength of incident light, and exhibits a wavelength selective optical response as a result of a strengthening, under resonance conditions, of optical coupling between the incident light and a surface plasmon mode which depends on the microstructure 11a. The microstructure 11a comprises a unit structure arranged with two-dimensional periodicity and rotational symmetry, and is polarization independent. A refractive index sensor 10 includes the metamaterial structure 11.
従来技術、競合技術の概要(英語) BACKGROUND ART
In recent years, various bio, chemical detection techniques have been developed in which, the refractive index of the surface plasmon resonance sensor has attracted attention. Using conventional surface plasmon resonance is the refractive index sensor, largely classified into two types. One thin film of gold (Au) on the surface plasmon propagation of a glass prism and using (for example, see Non-Patent Document 1 or 2), the other is a localized surface plasmon of the Au colloid is used with the present invention (for example, see Non-Patent Document 3).
