Defines a time-harmonic, singular electric current density on a z-coordinate directed line,

\begin{eqnarray*}
\VField{J}(\pvec{x}, t) & = & \VField{j} \delta \left( [x, y]-[x_0, y_0] \right) e^{ik_z (z-z_0)}e^{-i \omega t}
\end{eqnarray*}

Here, \omega is the the angular frequency, k_z is the wave vector in z -direction, \pvec{x}_0 = [x_0; y_0; z_0] is the position of the line source and \VField{j} is a constant strength vector. These parameters are set using the keys Omega, KZ, Position, and Strength, respectively.

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