Abstract

Scattering in water-paraffin oil emulsions was studied by terahertz time-domain spectroscopy (THz-TDS) with the aim of estimating droplet size and concentration. The loss coefficients in water-oil emulsion systems were measured at very low concentrations of water (≤ 1% v/v) to establish the sensitivity of THz-TDS. As expected, the scattering losses increased linearly with water concentration. The scattering spectra exhibited a quadratic dependence on frequency, indicating that Mie scattering was the dominant scattering loss mechanism in this system.
