2014 Advanced Computing An International Journal  
from a mobile phone at frequencies 900 MHz Mobile Phone model with a λ/2 monopole antenna and a hand head phone model dimensions are 100 mm x 50 mm x 20 mm.  ...  The head model used is a sphere with a diameter of 18 cm. The FDTD grid size used in the computation was 2.5 mm. The distance between the antenna and head was 5 mm.  ...  Such calculations have shown that, during normal operation, a radiated power of 1 W gives rise to a maximum SAR of 2.1 W kg -1 at 900 MHz and 3.0 W kg -1 at 1.8 GHz averaged over any 10 g of tissue.  ...
