Hello.
I am an absolute beginner to COMSOL and am hoping to eventually use it to simulate some nanoparticle scattering effects for solar cell applications.
I have built a very simple model consisting of an Air - Glass - Air geometry and have excited a wave at a port on one of the Air sides. I've included PML and a suitable mesh. I see that the wave propogates through the air, into the glass (wavelength reduces by a half as n = 2.05 in glass) and back out into the air.
I would like to know a good method of proving the well known Fresnel equations for Reflectivity (n1-n2)/(n1+n2) mod all squared.
So far I have done line integrations at each boundary looking at Power Averages, and Ez, but I am not getting data that arrives at my calculated answers. Can anyone recommend a strategy for proving that the intensity of the wave obeys the Reflection/Transmission values calculated by hand?
Many thanks.
