Abstract

See full text

An electronic field enhancement element includes: a metal layer; a dielectric layer provided on the metal layer; and a plurality of fine metal structures provided on the dielectric layer. A refractive index n of the dielectric layer satisfies n′=n+iκ and is in a range of 1≦n<1.46, wherein a complex refractive index of the dielectric layer is n′, an imaginary unit is i, and an extinction coefficient is κ.
