RSim     Periodic layer (Bragg Mirror)

Here we simulate two quarter wave layers, one with low index n1= 1.30 and one with high index n2=1.8. The design wavelength is lambda = 600nm. The two layer unit is repeated twenty times ( set the stack period to 20).
The light is reflected to 100% around the design wavelength. Try to play with the number of repetitions.
