[12a-S421-8] Terahertz Absorption Spectra of FeOOH

〇Tadao Tanabe¹, Ryo Hasegawa¹, Akio Shiota¹, Yutaka Oyama¹ (1.Tohoku Univ.)

Keywords:THz NDT, steel, corrosion

Our group has created a database of THz spectra for industrial materials, and successfully constructed non-destructive THz diagnosis of hot-dip galvanized steel sheet. In this study, the terahertz absorption peak due to the infrared activity of β-FeOOH was obtained.
