How setting flux plane in cylinder...
I want to obtain spectra in fiber bragg grating
so I calculate in cylinderical coordinate
but i difficault in flux shape
Meep example explained only flux box in fiber
that is not good for me.
flux plane 2D (R) flux plane 2D (T)

How setting flux_plane in 2D (fiber)
....
....
vec ld(veccyl(-rmax*3/3, R_pt)), lu(veccyl(rmax*3/3, R_pt)); //?
vec rd(veccyl(-rmax*3/3, T_pt)), ru(veccyl(rmax*3/3, T_pt)); //?
geometric_volume flux_plane_R_cyl(ld, lu); //??
geometric_volume flux_plane_T_cyl(rd, ru); //?
dft_flux ft = f.add_dft_flux_plane(flux_plane_T_cyl,freq_min, freq_max, nfreq);
dft_flux fr = f.add_dft_flux_plane(flux_plane_R_cyl,freq_min, freq_max, nfreq);
dft_flux ft0 = f0.add_dft_flux_plane(flux_plane_T_cyl,freq_min, freq_max, nfreq);
dft_flux fr0 = f0.add_dft_flux_plane(flux_plane_R_cyl,freq_min, freq_max, nfreq);
Thank you.
