我们提出了由浸没在向列相液晶中的特殊线栅组成的电可调谐杂化超材料。由于通过施加到导线的外部电压切换液晶排列，该结构的类等离子体介电常数可以基本改变。根据结构的大小，这种效应在微波和光学频率范围内都可用。
We propose electrically tunable hybrid metamaterial consisting of special wire grid immersed into nematic liquid crystal. The plasmalike permittivity of the structure can be substantially varied due to switching of the liquid crystal alignment by external voltages applied to the wires. Depending on the scale of the structure, the effect is available for both microwave and optical frequency ranges.
