This lecture describes an algorithm to spatially vary a periodic structure. That is, attributes such as orientation of the unit cells, lattice spacing, and fill fraction can be made to vary as a function of position. The overall lattice is kept smooth, continuous, and defect free. Undesired deformations are minimized.
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.
