“…Liquid crystal’s (LC) optical properties are electrically tunable, and therefore they are attractive for displays [ 1 , 2 , 3 , 4 , 5 , 6 , 7 , 8 ], spatial light modulators [ 9 , 10 , 11 ], laser beam steering [ 11 , 12 , 13 ], lenses [ 14 , 15 , 16 ], filters [ 17 , 18 ], etc. A crucial parameter of LC materials is their dynamics.…”

Liquid crystal materials composed of mixed nematic compounds find broad use in liquid crystal displays and photonic applications. A ternary mixture formed from three different nematic compounds shows peculiar behavior such as tunable electro-optical properties dependent on the frequency of the driving voltage. The paper presents an analysis of the response time and phase retardation of a frequency tunable nematic liquid crystal mixture (under code name 5005). This material possesses high birefringence (Δn = 0.32 at 633 nm) as well as high dielectric anisotropy (Δε = 6.3 at 100 Hz). The unique property of the 5005 mixture is frequency-controlled phase modulation, as in a dual frequency liquid crystal, while dielectric anisotropy goes to zero instead of being negative at high frequencies. For each component of the mixture, details on mesomorphic properties and their role in the formulation of the mixture are reported. The 5005 mixture was characterized by multiple investigation techniques, such as temperature dependence dielectric anisotropy, transmittance measurements image polarizing microscopy, and UV stability.

“…Voltage gradient can be created by a complex manufac− turing process designing a set of electrodes across a thick− ness−reduced lens and applying zonal control [11]. Pat− terned electrode method has been reported using dielectric layers between the electrodes and the LC layer causing a parabolic voltage gradient only with optimized distances [12,13]; however, drawback is high control voltages (>50 V rms ).…”
