Abstract: Terahertz electromagnetic waves become a very useful tool for nondestructive testing of glass-fiber reinforced composite materials. In this paper we deal with detection abilities of defects which may arise in the mentioned structures. Terahertz time domain measurements enable us to gain an information about interior part of multilayered materials. In order to flaws detectability evaluation finite element method simulations were carried out. Numerical analysis was verified by measurements of multilayered reference structures.

Keywords: THz waves time domain measurements, composite materials, THz wave propagation numerical modeling
