Passively Tunable Terahertz Filters Using Liquid Crystal Cells Coated with Metamaterials
Liquid crystal (LC) cells that are coated with metamaterials are fabricated in this work. The LC directors in the cells are aligned by rubbed polyimide layers, and make angles <i>θ</i> of 0°, 45°, and 90° with respect to the gaps of the split-ring resonators (SRRs) of the metamaterials....
