Title:
PHASE DIFFERENCE ELEMENT, PHASE DIFFERENCE ELEMENT MANUFACTURING METHOD, AND OPTICAL MEMBER
Document Type and Number:
WIPO Patent Application WO/2017/195810
Kind Code:
A1
Abstract:
The purpose of the present invention is to provide: a phase difference element that has high ellipticity and high transmittance and that is easily machined; a phase difference element manufacturing method; and an optical element that uses the phase difference element. A phase difference element 10 for controlling the optical characteristics of an incident electromagnetic wave is provided with: a metal part in which linear metal structures 1 having widths smaller than the wavelength of the electromagnetic wave are periodically arranged in parallel; and a dielectric part 2 that supports the metal structures 1 and that comprises a dielectric body through which electromagnetic waves can pass.
