Abstract :
This paper investigates the effects of metallic jewellery on the SAR in the human head. A CW dipole is placed in front of the head to represent a mobile enabled personal data assistant. The FDTD method has been used to simulate an eyebrow ring near a homogeneous SAM phantom at 1.8 GHz. Measurements were made on the Loughborough SAM head with the DASY4 measurement system. Simulations were also made with eyebrow rings on the surface of the skin and pierced through the eyebrow of a heterogeneous anatomically realistic human head. Common sizes of eyebrow ring and eyebrow stud have been considered over the frequency range 0.6 to 4.6 GHz. Jewellery which was small compared to a wavelength had little effect on the SAR in the head.
