This lecture builds on previous lectures to discuss the physics and applications of photonic crystals (electromagnetic band gap materials). A basic definition is given and then the physics leading to the band gap is discussed along with the conditions for complete band gap are outlined. Dispersion engineering in photonic crystals is discussed along with self-collimation.
This course by Dr. Raymond C. Rumpf is intended to teach students about electromagnetic devices and how they may look and operate in coming decades. Special attention will be paid to periodic structures, metamaterials, and structures fabricated by 3D printing. Devices will be designed and analyzed using tools developed during the prerequisite course “Computational Electromagnetics” as well as some new tools developed in this course.
