|
Probe architecture |
– Electric (E-) field, 3 x orthogonal axis isotropic for V/m assessment – Magnetic (H-) field, 3 x orthogonal axis isotropic for A/m assessment – Combination of (E) & (H) for correct Power density (S) in W/m2 or mW/cm2 – Results displayed as percentage of RF exposure standards |
|||||||||||||||||||||||||||||||||||||||||||||||||
|
RF Exposure conditions |
– Near field (close to antenna), E-field & H-field components unrelated and individually assessed for safety compliance to radiated standards, especially for low frequency FM & Television transmitters – Far field (further from antenna), E- & H-field related as per free space and assessed accordingly – Multiple concurrent sources of RF, both near & far field correctly assessed and combined to present a single cumulative result in terms of relevant RF exposure standards. |
