This paper demonstrates the relationship between industry (Swisstulle Ltd) and two independent departments at DMU. Novel textile structures were developed that reflect or absorb microwave radiation. Textile structure, hole size, conductive yarns or conductive coatings have been manipulated to optimise performance. Fabrics characterised over a wide range of wavelengths demonstrated shielding potential of optimised structures which may be fine tuned. Swisstulle fabrics are used in conductive circuits and screening applications. The possibilities of using textiles for electromagnetic shielding, transmission lines and conductive circuits are being taken further – proposal to EPSRC prepared with link to US manufacturer Tectronix investigating textile antennas.
