Experimental study of scattering effects of THz waves by clothes

E. Hérault, Ch. Ketchazo, J.-L. Coutaz


Detection of dangerous or prohibited substances is one of the greatest applications expected in the THz domain. In this context, interaction between fabrics and THz waves is of prime importance. We propose in this paper an experimental method to characterize the radiometric response of fabrics, which is illustrated by the case of linen. In particular, by using a goniometer THz-TDS setup, we are able to measure the signal scattered by the sample. We then determine the absorption coefficient of linen. Our results strongly differ from those obtained by a classic THz-TDS setup for frequencies above 0.9THz

Some signal is lost by depolarization through the fabric as observed in another experimental work not reported here, as the incident THz beam is linearly polarized and the receiving antenna is polarization sensitive. To take into account this effect that is observed only when scattering appears, we have mutliplied by 2 the measured value of the scattered signal Ist.
