The Antenna Toolbox provides the 'planeWaveExcitation' function. This is used to solve the scattering problem associated with a receive antenna. I would like to know how to set or scale the plane wave incident power on the antenna? The Object Function 'feedCurrent' must assume a 'normalized' plane wave incident power. So for example, if I want to calculate the feed current for a received incident power of 1uW, what shoud I scale?
h = planeWaveExcitation;
cur = feedCurrent(h, 70e6) % How to scale this to get result for a specific incident power?

The Polarization property of the planeWaveExcitation function can be used to set the incident wave's magnitude in the units of V/m. For an incident wave power of 1uW the calculation has to be done to convert it to V/m and then specify it in the Polarization property.
h = planeWaveExcitaion('Polarization',[0.02 0.02 0.02]);
cur = feedCurrent(h,75e6);
Hope this helps!
