Dielectric Properties of Copmosite Material Single Crystal KDP Matrix with Incorporated Anatase Nanocrystals in Terahertz Spectral Region

Abstract

Dielectric properties of new composite material single crystal KDP matrix with incorporated anatase nanocrystals were investigated by terahertz time-domain spectroscopy in a wide temperature range. It was shown that anatase nanoparticles significantly effect on dielectric properties of KDP crystals in THz range. It was obtained that dielectric permittivity drastically changes at the temperature below phase transition
