Abstract :
By considering the full electromagnetic field expressions for the electric and magnetic dipole, a radiation transmission efficiency is defined for each dipole without restricting the solution to either the near or far field zones. It is shown that the transmission efficiencies of the electric and magnetic dipoles are the same across all possible distances, both near and far field. The role of frequency and spatial location on the transmission efficiency is also explored.
