Angular distribution of electric dipole radiation (source code)

= Angular distribution of electric dipole radiation

If $\theta$ is the angle between the observation direction and $\ddot p$, then
$$
\frac{dP}{d\Omega}
=\frac{\mu_0}{16\pi^2c}|\ddot p|^2\sin^2\theta.
$$
Integrating over <solid angle> uses $\int\sin^2\theta\,d\Omega=8\pi/3$ and gives the total <electric dipole radiation> power.
