Abstract

Transmittance of 'Gore-Tex' woven radome membranes with various diameter of threads and thickness of the laminate has been studied as a continuous function of frequency over the range 90-900 GHz by utilizing Fourier transform spectroscopy. For the first time the transmittance has been measured with various angles of incidence of the incident wave. Strong diffractive scattering has been found above the frequency with wavelength comparable with period of the fabrics. Gore-Tex woven membrane materials are suitable for radome applications up to 1000 GHz.
