Hi there, Maybe this is a stupid question. Maybe not. I want to make a statement in my thesis that says that all radar antennas on satellites derive the EM field by: receiving the time-varying H field, and from the induced current derive the EM field. Am I correct in saying that? Or are there any different types of antennas? The reason I ask, is because I want to make a statement for noise induced in certain scenarios where the H field lags the E field.
