Abstract
- The particle sizes and porosities of simulated pore structures are probed by terahertz time-domain spectroscopy. A double-peak time-domain spectrum phenomenon is observed when the terahertz (THz) pulses illuminated a pore and a particle. The amplitudes of the two peaks depend strongly and monotonically on the particle size and porosity. A model is used to study the phenomenon, and the computational results agreed with the experimental measurements. These measurements indicate the terahertz spectroscopic behaviors of pores and particles, suggesting that terahertz spectroscopy can be used as a noncontact probe of porosity. [ABSTRACT FROM AUTHOR]
