The cumulative effects of different sources on the human body

Everyday, people are dealing with different sources that produce electromagnetic field (EMF) with various frequencies, thus they become exposed to EMF radiation that might be harmful. The effect of these radiations on human body can be studied by measuring the Specific Absorption Rate (SAR) which is the rate at which EM energy is absorbed by the tissues. This paper determines the maximum 1-g SAR by simulating MATLAB code using the finite-difference time-domain method (FDTD). Then it distinguishes between the effect of exposure to EM waves with single frequency and multi-band frequencies. We found that the effects on the human tissues have been increased with using multi-band frequencies.
