Metals have an index of refraction but interact differently than most materials due to the imaginary part. Metals also tend to be highly reflective. My question is if a layer of aluminum (n=1.2) is deposited on glass (n=1.5) and light is incident from inside the glass at different angles, is the light reflected by the metal surface at angles below the critical angle and is the light reflected by internal reflection above the critical angle? If so, for angles below there should be a few percent loss from reflection and at angles above it should be a perfect reflection. Is this correct? Could you provide references for further study? Thank you!
