This tutorial is a practical example how the Electromagnetic Wave module (RF) can be used to simulate an electromagnetic wave in a dielectric. It is shown, how the light is refracted or reflected at the dielectric-air interface. Simulation is done for different incident angles. It is clearly seen, when total internal reflection sets in and when refraction happens. Plotted and exported graphs:
normalized timeavaraged power flux: sqrt(emw.Poavx^2 + emw.Poavy^2 + emw.Poavz^2)
and the z component of the electriomagnetic wave: Ez

These Tutorials were created to get you going with COMSOL 4.2. The aim is to show basic principles, how to use the tools, how to extract data and so on. For each field of simulation you should however, have a good knowledge about the theory.
