Title:
WIRE GRID DEVICE
Document Type and Number:
WIPO Patent Application WO/2015/029868
Kind Code:
A1
Abstract:
An objective of the present invention is to easily achieve an extinction ratio in the approximate 10-6 class for intensity transmittance in the terahertz band with one element. Provided is a wire grid device, configured from layering a plurality of film substrates (10) each formed from a rectangular polymer film (11) wherein a narrow rectangular metal thin plate (12) is formed in the approximate center of one face thereof. By having the width (a) of the metal thin plate (12) be approximately 1.0mm, the length (l) of the metal thin plate (12) be approximately 12.0-30mm, and the thickness (d) of the film substrate (10) be approximately 0.5-50μm, it is possible to easily achieve an extinction ratio in the approximate 10-6 class for intensity transmittance in the terahertz band with one element.
