Computes the radiative power of a far field through rings of the far field hemisphere.

Warning

The precision of the integration depends on the accuracy of the far field export. To improve the precision use the parameter NRefinements to increase the sampling rate of far field export.

Depending on the chosen NumericalAperture during the far field export the far field is defined for $0 \leq \vartheta<\vartheta_{\mathrm{max}}$ and $0 \leq \varphi \leq 360^{\circ}$ . This circular range is subdivided into NRings,

The output of the post process is a JCM table with energy fluxes $P_{l}^{(i)}$ .

Storage format

Each row corresponds to one polar-angle ring of the far-field hemisphere (or a signed angular interval in the 2-D case):

Columns 1–2: Theta1, Theta2

Lower and upper polar-angle limits of the ring.
Columns 3–…: Radiation_<iF>

Integrated radiative power of field iF through that ring.
