Hi meep users
I want to get the energy flux in dielectric medium about different
wavelength
So I use ‘flux-in-box’ to get the poynting vector integral results.
Other conditions are same. I just change only the wavelength.
For example, if I put the wavelength 0.44, the integral results have ‘0.01
- 0.02’ range
But, if I put the wavelength 0.52, the integral results have ‘2 - 2.5’
range.
It is a very big difference
I can’t understand this results
I hope your advises.
My ctl file is below.
Thanks in advance
Cho.
