Title:
シート型メタマテリアルおよびシート型レンズ
Document Type and Number:
Japanese Patent JP6596748
Kind Code:
B2
Abstract:
This invention is intended to provide a sheet-type metamaterial of a film configuration to exhibit a figure of merit (FOM) exceeding 300 in a terahertz wave band. A film-shaped dielectric substrate 12 has a front surface on which a first wire array 10 is formed, and a back surface on which a second wire array 11 is formed. The first wire array 10 includes elongated metallic first cut wires 10a of a predetermined length l aligned in a y-axis direction with a gap g therebetween and in an x-axis direction with space s therebetween. The second wire array 11 includes second metallic cut wires 11a having the same shape as the first cut wires 10a and aligned so as to overlap the first cut wires 10a. With a thickness d of the dielectric substrate 12 set at about 50 µm, the length l of the first cut wire and the second cut wire is a length approximate to a value to generate resonance at a design frequency.
