Terahertz Insights Into Fabric Look-Through

This study investigates the interaction of natural, synthetic, and blended fabrics with THz radiation using THz-TDS and THz-FDS measurements in the 100–1000 GHz frequency range. Based on the measured transmission response, refractive indices and Fresnel transmission coefficients are derived to assess the wave-transparent and wave-absorbing behavior of different fabric materials.

The results provide insight into the electromagnetic properties of fabrics and their potential use in technical applications, including biomedical systems, wearable technologies, and security screening. By combining time-domain and frequency-domain THz measurements, the study establishes a basis for evaluating multilayer textile structures under realistic propagation conditions. The accompanying dataset includes the time-domain information of an Airmesh fabric sample measured using THz-TDS.
