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) resonance modes of the finite-leng... https://foldlyers.shop/product-category/battery-accessories/
