One-dimensional photonic crystal dispersion relations

Calculates and plots the dispersion relations of elmag. waves in a 1D photonic crystal (PhC) for bot

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.
