Frequency selective solutions for an efficient non-ionising radiation protection in the radiofrequency and microwave ranges.
The paper introduces an efficient solution for the realisation of frequency-selective devices which can shield non-ionising radiation in the radiofrequency and microwave bandwidths. The identified hardware is transparent to visible light and it can be adapted to the shielding needs, both in terms of frequency and spatial behaviours. Being transparent, it can be effectively applied on windows that normally offer the worst attenuation coefficient to outdoor versus indoor penetration. The solution exhibits enhanced performance, it can be analysed with fast but exact numerical techniques and it can be manufactured by low-cost industrial procedures. To demonstrate the validity of the approach, an example has been designed, analysed and applied to the frequency spectrum occupied by upcoming wideband access base stations.
