Wideband ultra-high refractive index mesoscopic crystal structure using space-filling of electric dipole and optical device using the same

A wideband ultra-high refractive index mesoscopic crystal structure using space-filling of an electric dipole, comprising:

• a first layer in which a plurality of high-conductivity unit bodies is arranged in a matrix form, and a low-conductivity material is disposed between the high-conductivity unit bodies to insulate the high-conductivity unit bodies from each other;
• a second layer in which a plurality of high-conductivity unit bodies is arranged in a matrix form, and a low-conductivity material is disposed between the high-conductivity unit bodies to insulate the high-conductivity unit bodies from each other;
• a first shield layer existing between the first and second layers and made of a low-conductivity material;
• and
• a second shield layer made of a low-conductivity material and disposed on a side of the second layer such that the second layer is disposed between the first shield layer and the second shield layer,
• wherein, the high-conductivity unit bodies in the first layer overlap the plurality of high-conductivity unit bodies arranged in the second layer, and
• wherein the first layer, the first shield layer, the second layer, and the second shield layer are sequentially stacked one or more times.
