Defines a time-harmonic dipole sources at a given point \pvec{x}_0, e.g.,

\begin{eqnarray*}
\VField{M}(\pvec{x}, t) & = &  \VField{m}  \delta \left( \pvec{x}-\pvec{x}_0 \right) e^{-i \omega t}
\end{eqnarray*}

Here, \omega is the the angular frequency, and \VField{m} is a constant strength vector. These parameters are set using the keys Omega (or Lambda0), Position, and Strength, respectively.

The PostProcess DipoleEmission can be used to compute the total emitted power of a point or line source.
