hi berkeman ,this effect has confused me ,because i don't understand how it possible light to go less dense medium? from Snell's law we know undergoes of total internal reflection the light beam has to come back to the denser medium.so what is the physical interpretation of this penetration to...

1.What is the Goos-Hnanchen shift and how i can find some physical interpretation about this concept? 2.whats physically happens when light path throughout the second medium? 3.please introduce me some references to know more about this shift.

Hi And Need Help The main Question is what happens to light and cause go into next medium as total internal reflection happens for incident angles higher than critical angle ? so the main question is why the light path throughout the second medium? We know when light travels from a medium...

I have a question: when the poynting vector and energy propagation in electromagnetic waves are in the same direction and when are in different direction?

what physically means the Trace of a Matrix? dose it has a physical concept?
