Phonon-polariton dynamics in sodium silicate glasses investigated by terahertz time-domain spectroscopy

POSTER

Abstract

We investigated phonon-polariton dynamics in the sodium silicate glass system using terahertz time-domain spectroscopy. Then, using a novel damped harmonic oscillator model in which an attenuation term with wavenumber dependence was introduced, the dielectric response in the terahertz region, especially the absorption behavior owing to the boson peak, was investigated.
