Design of a Liquid-Crystal-Tunable Terahertz Demultiplexer Based on a Metal-Insulator-Metal Waveguide
A tunable demultiplexer with three output channels infiltrated by liquid crystal (LC) is presented, which is based on a metal-insulator-metal (MIM) waveguide.The operating frequencies of the three output channels can be tuned simultaneously at will by changing the external bias electric field applied to the LC.By analyzing the Fabry-Pérot (FP)
