Hello, Thanks for your answers.

What frequency range is used for the calculation of Power Density in Watts/m² or pico Watts/cm², etc.

Thank you.

Hi Frank, for RF the frequency range is 10MHz - 10GHz.

One last thing.
People I talk to often request flux density in V/m.


Would it be correct to calculate V/m by using formula
square root of (measured Watts per m² * 377)

In other words, is 1mW/m²
= square root of (1 / 1000 * 377)
= 0,61400325732035 V/m

in the frequency range of 10MHz - 10GHz?


Thank you again.
