Abstract: The multilayer structure of an ultra- high molecular weight polyethylene composite material was investigated in the terahertz (THz) spectral range by means of time domain spectroscopy (TDS) technique. Such structures consist of many alternating layers of fibre (~150), each being perpendicular to the other and each having thickness of about 50 micrometer. A transfer matrix method (TMM) and a time domain fitting procedure were used to determine thickness of all layers of the composite material with high accuracy. We apply this technique for various other materials
