Consider a uniform plane wave impinging obliquely on an air-to-glass (εr = 4.0) boundary from the air side of the boundary. The boundary is flat and the dielectrics may be considered to be infinite in extent on both sides of the boundary. The incident wave is polarized in the plane of incidence. Find the incident angle for which total absorption takes place. Would this also apply for a wave which is polarized normal to the plane of incidence? If yes,...

A plane-polarized electromagnetic wave in vacuum E (x, t) = E0eikx–iwt (in the epsilon-hat direction); cB(x, t) = k × E(x, t) falls at an angle of incidence θ on an infinite plane dielectric of finite depth, where its reflection coefficient is R (the ratio of the incoming Poynting flux to the reflected flux). Assuming all the refracted/transmitted electromagnetic wave is eventually absorbed in the dielectric (that is it does not pass out the other side) use the stress tensor...
