We have used terahertz (THz) time-domain spectroscopy to investigate the complex optical constants and birefringence of a widely used liquid crystal mixture E7 in both nematic and isotropic phases (26ºC~70ºC). The extinction coefficient of E7 at room temperature is less than 0.035 and without sharp...
