where c is the speed of light in vacuum, S = E×H is the Poynting vector, E0 and H0 are the amplitudes of the incident electric and magnetic fields, and Z0 = √ μ0/ 0 = 377 Ω (= 4π/c in Gaussian units). We also note that the small antennas are generally well described by their electric and magnetic dipole moments. So, we consider here the cases of a small linear dipole antenna, for which only its...
