摘要:
An optical material which has a relative permeability different from 1 to light having a wavelength in, for example, the infrared region or shorter than the infrared region and which is stable in structure, and a liquid and a solid (optical element) using the optical material. The optical material is a powder used as a component of a liquid or solid to which an illuminating light is irradiated, and includes a large number of resonating elements which constitute the powder and each of which is formed of a conductor having a width approximately same as or smaller than a wavelength of the illumination light, and a protective film which is formed of a disc-shaped insulator, wherein an entire surface of each of the split-ring resonators is covered by the protective film.
