PointSource¶

Type:	section
Appearance:	multiple

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

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

Here, $\omega$ is the the angular frequency, and $\VField{j}$ 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.
