Near field maximum
Near field maximum
(OP)
Hello,
In the farfield zone, we can approximate the electrical field by the formula E=sqrt(30*E.I.R.P)/distance
We also know that this value is a maximum of the field.
I was wondering whether this value could also be a maximum in the nearfield zone ?
If not, is there a way to approach the value of the electrical field in this zone ?
Thanks

In the far field all but the 1/d terms become very small. In the near field the other terms dominate. Also, E.radial is not ~0 in the near field as it is in far field.
Q2: I'm not aware of a simple equation, but perhaps someone else here has seen one.
