This Demonstration calculates the electric field transmission from a 1D photonic crystal that consists of alternating layers having refractive indices of

n

1

and

n

2

.

You can see the band gap phenomena. The dependence of the band gap width and transmission on the difference in

n

1

and

n

is evident.
