This lecture introduces slow waves. It starts by describing phase, group, and energy velocities from which the cause of slow waves is discussed. Media producing slow waves are dividing into resonant structures and pure material structures. An array of examples are given for each.
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.
