Embodiment
[0026] figure 1 A structural diagram of a unit array of a terahertz wave modulator based on atomic vacancy defects provided for the embodiment; figure 2 A top view structure diagram of a unit array of a terahertz wave modulator based on atomic vacancy defects provided for the embodiment. Depend on figure 1 with figure 2 It can be seen that the terahertz wave modulator of the embodiment includes a sapphire substrate with a thickness of 500 μm, and a metamaterial structure layer formed on the substrate; the metamaterial structure layer includes a plurality of metamaterial units arranged in an array, and the supermaterial structure layer The material unit is composed of four C-shaped resonant rings arranged in 2×2. The openings of the two C-shaped resonant rings in the first row are set opposite to each other, and the openings of the two C-shaped resonant rings in the second row are set in opposite directions; among them, The C-shaped resonant rings in the second row and the...
