-just as the flux $S\propto \sing^2\theta$ for a single accelerated charge. A **short** dipole behaves just like a point charge in this sense. If we want to find the total time-averaged power we have to perform a similar integration as we did in the //acceleration// article:

  $\langle P \rangle = \int \langle S \rangle dA = \frac{\pi^2}{3c} \left(\frac{I_0l}{\lambda}\right)^2 = \frac{\pi^2}{3c} (I_0 l_\lambda )^2$
