Hi All,
what is the reason why very close to an electromagnetic source (Fresnel Region), the wave impedance Z0 in free space for electric field and magnetic field is not the same? Z0 for magnetic field increases and for electric field decreases by increasing the distance from the source. Actually they are different also in the Frounhofer region but they have practically the same values with a very insignificant error.
So why the wave impedance can be different for the electric and magnetic fields?
Regards
Massimo
