2.ANALYSIS
Electromagnetic energy(EME)exposure situations have been modeled using the fallowing techniques.
The power density in the far field region of the antenna pattern decreases inversely as the square of the distance.The power density(S)in the far
field region of the radiation pattern can be calculated using the equation S=EIRP/(4trRA2). For atruly worst-case prediction of power density
at or near a surface,such as at ground level or on rooftop,100%reflection of incoming rdiation can be assumed,resulting in the potential
doubling of predicted field strength and a four-fold increase in the far-field equivalent power density S=EIRP/(7rRA2).
The cylindrical model in the near field is also used specifically for rooftop scenario where access near the antenna is possible.This model was used
to compute the average power density an the surface of an imaginary cylinder,with a height equal to the antenna's aperture and a radius equal to
the distance of interest.
