What's the amount of energy lost in Total Internal Reflection?

[QUOTE="Ibix, post: 6001085, member: 365269"] Indeed. My somewhat hazy recollection is that evanescent fields don't transport energy (the time average of their Poynting vector is zero), unless they end up overlapping into a medium that can support a normal electromagnetic wave again. So there isn't much of a mechanism for energy loss. There was a recent thread about evanescent waves in absorbing media. That might be worth looking up.
