Hi Kate,
Not sure about practical, but ISO 11452 Part 3 describes the calculation method
for the electric field inside a TEM cell.
It uses the formula
|E| = sqrt(P x Z) / d
Where |E| is the absolute value of electric field measured in Volts/m
P is the net power, in watts, to be understood as total forward power - total
reflected power, Z is the characteristic impedance of the TEM cell in ohms
( typically 50 Ohms) and d is the separation in metres, between the floor
and the septum of the TEM cell ( about half the height of the cell).
Regards
- Chris

Hi, Folks -
We have noticed that not everybody is using the same formula for calculating
E-field inside of a TEM cell.
Does anyone out there have practical formulas (and/or any other useful
information...) relating power to the E-field?
Many thanks in advance,
Cheers,
Kate
