The Specific Absorption Rate (the rate at which energy is absorbed by a unit mass) given in W/kg is calculated by the following equation
SAR = (sigma * Erms^2) / p
Where sigma is the conductivity of the material (given in S/m), Erms is the RMS electric field (V/m) at the location and p is...
If we assume the frequencies of the multiple sources are the same, where in the above equations would you take phase information into account. OR is it implied that simple power density additions cannot be done for same frequency sources?
The Power density (Pd in W/m^2) at a distance r (in meters) for a transmitting antenna with gain Gt is given by:
Pd = ( Pt * Gt) / 4 * Pi * r^2 where Pt (in Watts) is the power transmitted from the antenna.
All these variables are scalar values so if there were multiple antennas and...
