About Course

The aim of this course is to give an introduction to Photonic Crystals. Photonic Crystal are
widely used in many high end applications. In this course, we introduce the most important
concepts underlying periodic structures like photonic crystals, their applications, and
fundamental ideas. The course is intended for students and researchers with a knowledge of basic
quantum mechanics, electromagnetism and solid state physics. An attempt will be made to give a
concise mathematical background if and when required. Experience in simulation will be useful
