Hello,

I am fairly new to COMSOL and am hoping to use it to model the optics of components around a few wavelengths to sub-wavelength scales. I have worked my way through the plasmonic wire grating and photonic crystal waveguide examples (although the plasmonic wire grating example didn't produce the right results).

Does anyone have the Brewster's Angle example in 2D for v4.0a? I am looking to just start with some relatively simple optics before moving on to more complicated models. Or alternatively any advice on simple optics like Snell's law would be good too.

So far I am even unable to get a plane wave to propagate in a box of air using a scattering boundary condition to launch the wave and scattering boundary conditions or PMLs as absorbers around the edges.

Any help whatsoever would be extremely helpful.

Thanks in advance,
David
