I have measured the electric field radiations of coaxial connectors for a particular point using electric field probe, the signal analyzer show radiated signal results in dBm.
I have also simulated the model in CST, but it shows results in terms of electric field in V/m .
I want to compare simulated and measured results. How to convert units from dBm to V/m or V/m to dBm or convert both to V for better comparison and understanding.
Any guidance or any reference how to develop the transfer function?
No, they are not related.
But
dBm/square metre is related to V/m for a plane electromagnetic wave by the impedance of the medium it is travelling in.
Power density of 0 dBm/square metre = 1 milliwatt/square metre
A 1 V/m rms EM wave has an average power density of (1)2/Z watts per square metre,
where Z is the impedance of the medium, approximately 377 ohms for free space.
