FIG. 1.

Tunable broadside coupled SRR metamaterial based on anisotropic LC. (a) Schematic diagrams of basic unit cell and the reorientation of LC molecule in plane. (c) Schematic diagram of the assembly process. (c) Photograph of the SRR sample. The geometrical parameters of unit cell are as follows: , , , , , . Teflon fiberglass (, ) was chosen as host medium.
