Abstract
A sheet-type metamaterial includes: a film-shaped dielectric substrate; a first and second wire array formed on the dielectric substrate's front surface and back surface respectively. The first wire array includes elongated metallic first cut wires of a length 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 includes second cut wires having the same shape as first cut wires and aligned so as to overlap first cut wires and to be symmetric with the first cut wires. With a design frequency set at 0.51 THz, the dielectric substrate's thickness d is set at about 50 μm, space s is set at about 361 μm, gap g is set at about 106 μm, and the length of first and second cut wires is set at a length approximate to a value to generate resonance at a working frequency.
