A Theory for Analysis of Pulse Electromagnetic Radiation
A theory for analyzing the
radiative and reactive energies for pulse radiators in free space is presented.
With the proposed definition of reactive energies and radiative energies, power
balance at arbitrarily chosen observation surfaces are established, which
intuitively shows that the Poynting vector contains not only the power flux
density associated with the radiative energies, but also the influence of the
fluctuation of the reactive energies dragging by the sources. A new vector is
defined for the radiative power flux density. The radiative energies passing
through observation surfaces enclosing the radiator are accurately calculated.
Numerical results verifies that the proposed radiative flux density is more
proper for expressing the radiative power flux density than the Poynting vector.
