  Hi,
  How one can get power in the frequency domain from a time point source monitor? The "results" section of point source monitor has a "spectrum" dataset which contains the E and H fields data as a function of frequency (looks like an fft of E(t) and H(t) fields). But it does not have P for all these frequencies. Also i think point integration is not possible with integrate fuction?
  regards

  You can get the Purcell factor from the dipole source, which is dipower_radiated_power/source_power_in_homogeneuous_material
  source_power_in_homogeneuous_material can be obtained by sourcepower:
  sourcepower - Script command
  dipolepower - Script command
  Understanding dipoles in non-homogeneous materials
  Purcell factor of a microdisk
  You can also get the radiation spectrum from the point time monitor.
