Polarization Effect Assessment of Sub-6 GHz Frequencies on Adult and Child Four-Layered Head Models

Nowadays, with the extensive use of mobile phones, Electromagnetic (EM) radiation penetration from Radio Frequencies (RFs), particularly into human head, is an issue that needs resolving. Some serious biological hazards occur inside body due to RF accumulation. The can be minimized by embodying shielding and coating materials on front side handset. novelty proposed work mathematical analysis in calculating Specific Absorption Rate (SAR) absorbed planar four-layer adult child head models when exposed smartphone radiation. variation SAR Angle Incident (AoI) EM wave considers Transverse Electric (TE) Magnetic (TM) Polarization. absorption alteration AoI calculated help effectiveness parameter external Polyethylene Terephthalate (PET) shield coated conductive copper (Cu) mesh, forming a laminated using methodology transmission line method. Furthermore, for both theoretically at Sub-6 GHz frequencies 4.5GHz 3.6GHz. 7.41e-12 W/kg 4.41e-11 achieved respectively, 89° TE polarization 4.5GHz.
