N2 - The spectral characteristics of the terahertz band enable the identification of substances, which has a wide range of applications in security monitoring and defect detection. In practice, however, the measured substances are often occluded by other substances, resulting in spectral distortions that make accurate substance identification impossible. Based on the physical model of terahertz time-domain spectroscopy, this work proposes a terahertz spectroscopic measurement method for occluded substances. To demonstrate, we successfully measure the absorption spectrum of an aluminum oxide sheet placed below an aluminum nitride shell.
