comment Anomalous Total Transmittance
You can't get out more energy than you put in, so I would guess something's wrong with your calibration.

Cu nanocrystals embedded in glass, though, wouldn't be able to tell much about the solid metal, right?

comment Getting nonphysical results when solving for the index of refraction of a slab?
I was giving you long conjectures in the comments and finally I decided to stop conjecturing and make a real answer out of it ;-)

comment Getting nonphysical results when solving for the index of refraction of a slab?
What @SteveB says: It would not be at all surprising for this kind of data to be systematically shifted up or down a bit compared to reality. This has happened to me many times.

How did you normalize your R and T measurements? Out of curiosity, what happens with the computed n if you add an offset of 0.2 to either?

comment Optics - Faraday Rotator using waveplates
You can't. Waveplates are reversible, a Faraday rotator is not.

comment Why is the decibel scale logarithmic?
That's incorrect, the decibel scale is logarithmic: +10 dB gives 10x the sound pressure (and +3 dB gives about 2x, as you say) so +20 dB (100-80) gives 100x. In other words, $2^{(100-80)/3} \approx 100$.

comment Exciting Surface Plasmon-Polaritons with Grating Coupling
Take $\theta_o = \pi/2$, so the grating equation becomes $d(\sin\theta+1)=\nu\lambda$. Then $k=2\pi/\lambda$, and $g=2\pi/d$. The difference between $k$ and $\beta$ is because $\lambda$ is different for the surface plasmon.
