Metasurfaces and Metamaterials for Electromagnetic Wave Manipulation

Objectives
Artificial surfaces, metasurfaces, and Electromagnetic Skins are artificial sheet materials with sub-wavelength thickness that enable to control the properties of the transmitted/reflected waves according to the designer's specifications. Thanks to their electromagnetic and geometrical properties, these are among the most important technologies for the development of next generation wireless communications and sensing applications. The course aims at providing the fundamentals of Surface Electromagnetics theory and concepts, along with an overview of the most effective analysis/synthesis techniques and their most appealing/emerging applications in advanced engineering fields. Applicative examples including CAD exercises will corroborate the theoretical concepts.

Topics
Surface equivalence theorem and the concept of Surface Electromagnetics
Electromagnetic propagation through surface structures and 2D boundary conditions
Uniform surfaces, periodic and aperiodic boundary conditions and devices
The Generalized Snell’s laws for reflection and refraction
Electromagnetic wave manipulation using static/dynamic 2D artificial skins in transmission and in reflection
Applications for 6G communications and next-generation sensing systems

Required Skills
Course of “Foundations of Electromagnetic Waves”

Course Modality and Verification of Learning
The classes will be given in hybrid (i.e., onsite and online) format. The teaching activity includes theoretical lessons and SW/HW emulator exercises.
The exam consists of a written test with multiple-choice questions on the topics of the course.
