Tunable terahertz metamaterial filter

摘要

A tunable terahertz material filter is disclosed. The disclosed tunable filter material comprises a first grating wire and a second grating wire disposed in parallel with each other, a dielectric substrate and a liquid crystal layer sequentially formed between the first grating wire and the second grating wire, And a plurality of metal strips formed between the liquid crystal layer and a first control electrode and a second control electrode respectively connected to the first grid wire and the second grid wire to apply a voltage to the liquid crystal layer. The driving frequency of the filter can be adjusted according to the voltage applied to the liquid crystal layer.
