Abstract:
There is increasing interest in conducting fabrics and their uses at RF and
microwave frequencies. This paper for the first time looks at the reflection and
transmission measurements of bobbinet and knitted materials from around 8GHz
into the milli-metric frequency range 110GHz, where the material geometry is
comparable to the wavelength of the wave. Bobbinet materials were found to
behave like lossy dielectrics and may be useful in the construction of thin
light-weight screening and absorption planes. While the knitted materials, with
very small mesh geometry, gave a reflection coefficient which was comparable to
a metal foil.
