摘要：
The liquid crystal (LC) lens is prepared Using planoconvex-shaped metal substrates as electrically controlled quasi-optical millimeter-wave devices. The millimeter-wave focusing properties of the LC lens are calculated by the finite-difference time-domain (FDTD) method and measured at 94 GHz. The. focusing effects of the LC lens and changes in the focusing properties induced by the applied voltage have been obtained. The measured focusing properties of the LC lens agree with those calculated by the FDTD method.
