Thanks the help from someone about the calculation about the
reflection. But the sample on the homepage is in ctl and there is a
key function, load-minus-flux. But in C there's only load_hdf5. I
wonder whether they do the same thing. If not what should I do to
make load_hdf5 in C behaves as the load-minus-flux in ctl?
If you look in the meep.scm file, you'll see:
(define (load-flux fname flux)
(if (null? fields) (init-fields))
(meep-dft-flux-load-hdf5 flux fields fname "" (get-filename-prefix)))
(define (load-minus-flux fname flux)
(load-flux fname flux)
(meep-dft-flux-scale-dfts flux -1.0))
So, load-minus-flux in Scheme is the same as calling
dft_flux::load_hdf5 and then calling dft_flux::scale_dfts in C++,
where for the latter call you scale by -1.
