利用具有正介电各向异性和半圆形金属衬底的向列型液晶材料制作了液晶透镜单元作为准光毫米波器件。在94 GHz测量了LC透镜的毫米波聚焦特性，并观察到了透镜形状引起的会聚效应。证实了外加电场对聚焦特性的影响。
Liquid crystal (LC) lens cells are fabricated using a nematic LC material with a positive dielectric anisotropy and semicircle-shaped metal substrates as quasioptical millimeter-wave devices. The millimeter-wave focusing properties of the LC lens are measured at 94 GHz and its convergent effects caused by the lens-shaped configuration are then observed. Changes in the focusing properties by applying an external electric field are confirmed.
