Abstract: Human-friendly barriers against microwave radiation are designed using non-woven multiple layers of natural (flax) fibres, as well as flax and polypropylene fibre blends, with the split-ring resonators implanted so as to allocate the barrier properties in the pre-determined frequency band (X-band is selected for its applications in traffic radars and telecommunication). Oscillator model is proposed for determining the ring resonance frequency. The band of non-transmission up to ∼40 dB is observed. The band is found to shift depending on the flax and polypropylene contents in the blend, the distance between the ring centres, and on the number of textile layers.
