Thank you for answer.
I attach file what i have done.
I try something. I set source that is like RGB white LED spectrum.
I want to see the reflectance, but the amount of reflectance has changed with time.
I guess observation area estimate average of light. is it right?
When i see sample file, that use power spectrum to estimate reflectance.
And i want to know power spectrum y axis. is it power(W)? And then what is mean normalization in power spectrum. I think it is a bit different from what I think.
In conclusion, I would like to see a change in reflectance per wavelength depending on the source I made while changing the photonic crystal.
And I choose sine-modulated gaussian pulse, but In simulation summary, Input type is Gaussian Modulated Continuous Wave. I want you to send me the exact amount.
If there is a sentence that you do not understand, please let me know.
