I am simulating scatering properties of some particle.
For a size smaller than 35nm calculations run very well and I obtain
good results.
However when I increase the size of Nanoparticle to more than 40nm, at
the end of calculations
I obtain '+nan of -nan' as result (see this result below). I really do
not know what can be the matter.
Has anyone experienced this kind of problem? if it is the case, How can
I handle the problem?
There are four things you can try:
1) increase the resolution
2) reduce the Courant factor
3) if possible, reduce the number of Drude-Lorentzian terms
(note: you want the fit of the complex permittivity to be
accurate for just the spectra of interest using the
smallest number of terms)
4) replace any PMLs overlapping lossy metals with an 'absorber'
