This lecture discussed the use of gratings when the period is much smaller than the wavelength and only the zero-order mode exists. Such media are artificially anisotropic metamaterials and can be used for antireflection, wave plates, polarization control, and more.
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.
