Title:
SHEET TYPE METAMATERIAL AND SHEEET TYPE LENS
Document Type and Number:
WIPO Patent Application WO/2017/150098
Kind Code:
A1
Abstract:
This sheet type metamaterial has a first wire array 10 formed on the front surface of a film-like dielectric substrate 12 and a second wire array 11 formed on the back surface of the dielectric substrate 12. The first wire array 10 is constituted of long, thin metal first cut wire 10a of a length l at a spacing g along the direction of the y axis and a spacing s along the direction of the x axis, and a second wire array 11 is constituted of a second cut wire 11a in a symmetrical disposition with the same shape so as to overlap the first cut wire 10a. When the design frequency is 0.51 THz, the thickness d of the dialectic substrate is 50 µm, spacing s is approximately 361 µm, spacing g is approximately 106 µm, and length l for the first cut wire 10a and the second cut wire 11a is a length substantially resonant at the frequency used. Thus, a sheet type metamaterial with an index of refraction of zero can be obtained.
