Analyzing 2D Photonic Crystals Introduction

The tutorial demonstrates analysis of 2D photonic crystal using PWE Band solver.

First we create a lattice model of dielectric cylinders (permittivity=8.9) suspended in air. We then proceed with a simple simulation on a predefined k-vector path and result analysis. Finally we discuss the meaning of the Domain Origin in the PWE dialog box.
