Abstract:
In this paper, a new ultra-thin flexible absorber based on a novel tetra Y-inspired metamaterial unit cell is designed for human body protection from electromagnetic (EM) field Hazard and (EM) Thermal Impact. The polyimide Kapton film is used as the substrate for its mechanical and thermal advantages. The simulation results show that the proposed Flexible Metamaterial Absorber (FMA) features a high absorption peak at 5.2 GHz with the absorptivity of 98%. The simulation investigations confirm that the FMA sample is polarization insensitive for transverse electric and transverse magnetic incident waves. They also exhibit that high absorption for wide angle of incidence up to 75°. The same results feature a high and stable absorptivity for conformal configurations with an absorptivity value near 99% at 5.25 GHz. The experimental results of fabricated FMA samples using inkjet-printing technology show a resonant behavior around 5GHz with 70% measured absorptivity.
