Inorder to compute coupling coefficient , I need to estimate both odd and even refractive index values for a set a wavelength using comsol. I had already got n effective value, but how to evalute odd neff and even neff in comsol?
The class of how to obtain the mode distribution of the standard index fiber is inclued in the model help in COMSOL.
Do you mean the effective index foe even modes and odd modes in fiber?
Not in fiber, odd and even modes in Si waveguides
We are doing a study on impact of aerosol on precipitation. Which satellite data and which wavelength will be the best. or can some one suggest a criteria to be adopted to choose an instrument...
