I want to calculate a Purcell factor distribution (P_x,P_y,P_z,f) in the grid points as following image.
In the Green’s function example in the KX webpage, the matrix size of the simulated Purcell factor is (num_freq,1) where the num_freq is the number of the frequency points. It only contains a 1D result; the calculated Purcell factor is a function of z-axis. How I can get the 3D spatial field distribution of the Purcell factor in the FDTD simulation?
Here I attached the reference article.

Thanks in advance.
