This program calculates and plots the dispersion relations of elmag. waves
in a 1D photonic crystal (PhC) for both "s" (TE) and "p" (TM) polarization states
The 1D-PhC has a unit cell made of two different dielectric materials (known as Bragg mirror)
The propagation angle in one medium is taken as input
