This lecture builds on prior lectures to describe diffraction gratings and associated devices. The grating equation and diffracted modes are presented. The lecture ends by showing how patterned fanout gratings are designed using the Gerchberg-Saxton algorithm.
Prerequisite Topics: Lecture 7, Electromagnetics, and "Computational Electromagnetics"
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.
