Wearable metamaterial for electromagnetic radiation shielding

A novel wearable Frequency Selective Surface (FSS) created using fabric materials capable of blocking electromagnetic radiation around the frequency 10.64 GHz (X Microwave band) is presented in this paper. Two different unit cell shapes are tested: embroidered metal yarn squares and hexagons. cotton with permittivity 1.9 thickness 0.4 mm used as a substrate. The proposed design validated by comparison 3 D simulations measurements. obtained results correspond to maximum absorptivity 99.23% at 10.63 for simulation square cell, whereas hexagons led 99.94% 10.68 GHz. Experimental results, their turn, showed maximums 98.39% 98.00% hexagons, both 10.46 So, that textile was actually offering high degree shielding, increasing safety civil occupational exposures radiation. In case, protection offered microwave frequencies, especially telecommunications Earth-satellite which range considered potential risk WHO (World Health Organization).
