ECTS - University of Pisa
The student who successfully completes the course will have the ability to understand electromagnetic phenomena related to the propagation of electromagnetic waves in periodic structures comprising dielectrics and metallic particles.
During the oral exam, the student must demonstrate a solid knowledge of the course material and discuss the reading matter thoughtfully and with propriety of expression.
Student will be able to understand the theoretical aspects of artificial electromagnetic materials.
Oral exam.
Students will acquire a methodological approach to face the interactions of EM wave with complex materials.
INTERACTION OF ELECTROMAGNETIC WAVES WITH COMPLEX MEDIA
Face to face lectures with slides provided by the teacher.
METAMATERIALS (3 CFU):
Mixtures: Mixing rules and computation of effective permittivity (Maxwell-Garnet formulation); Metamaterials: Wire media, Split Ring Resonators (SRR) and double negative materials (DNG); Gradient metasurfaces: Gradient 2D metasurfaces for desingning flat lenses and reflectarrays and focoused EM sources; CRLH media: composite Right Left Handed (CRLH) transmission lines for the design of metamaterials and Electromagnetic Bandgap Surfaces (EBG).
Electromagnetic elementary sources: electric dipoles and magnetic loops. Electromagnetic sensors. Magneto-static approximation: biot-savart. Mutual induction. Magnetic metasurfaces of finite size: unit-cell design, equivalent circuit description. Metasurfaces excited by a near-field source: effective magnetic permeability, border effects compensation and metasurface frequency response analytical control. Introduction to electromagnetic numerical solvers.
