Sensitive measurement of water content in dry material using low-frequency terahertz time-domain spectroscopy system equipped with micro-structured photoconductive antennas

摘要

We proposed sensitive measurement of water content in dry material using low-frequency THz time-domain spectroscopy. Simultaneous use of micro-structured bowtie-type photoconductive antennas for generation and detection of THz pulse enables to achieve water content measurement in dry materials.
