| Abstract: | Lead magnesium niobate titanate is an important ferroelectric material. In this study, the terahertz (THz) transmission properties of a 0.73Pb(Mg1/3Nb2/3)O3–0.27PbTiO3 single crystal were investigated using a time‐domain spectroscopy method. Complex refractive index and dielectric dispersion functions were determined from the amplitude and phase information derived from time‐domain responses. Based on calculations, it was concluded that the room‐temperature dielectric constant of the single crystal equal to ~30 at 1 THz. This result could be a useful reference for development of ferroelectric‐material‐based THz components and devices. |
