TERAHERTZ WAVE MODULATOR BASED ON METAMATERIAL

摘要

A first pattern is a metamaterial structure formed in a square ring shape on a thin film made of a material resonating in response to a terahertz wave and changing dielectric-metal phase transition or permittivity according to temperature. And a voltage application conductor extending outward from the first pattern at the center of two opposing sides of the first pattern to cause a change in characteristics of the phase change material and the metamaterial. Modulator.
