ECTS - University of Pisa
The student who successfully completes the course will have the ability to understand electromagnetic phenomena related to time-varying electromagnetic fields. He or she will be able to demonstrate a solid knowledge of the characteristic parameters of the electromagnetic wave propagation as well as of the wave interaction with materials; the student will be aware of the techniques, such as discrete Fuorier trasnform, used to analyze wave propagation in complex materials characterized by frequency dispersion. The student will have knowledge of retrieving apporaches for computing dielectric and magnetic properties of materials and will understand how to desing a sensing device. He or she will have a basic knowledge of materials formed by periodic structures formed by dielectrics and metallic particles. In particular, photonic bandgap materials and frequency selective surfaces are treated.
During the oral exam, the student must be able to demonstrate his/her ability to report and expose on a project assigned by the teacher at the end of the course. Moreover, 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 extract the most important concepts from advanced topics. He will be also able to prepare a code for solving a practical EM problem and to presents the results though a brief presentation and a short report.
Oral exam and discussion about a project assigned by the teacher at the end of the course.
Students will acquire accuracy and precision when collecting and analysing experimental data.
During group work, the methods of assigning responsibility, management and organisation during the project phases will be evaluated
Transmission and reflection of plane waves on interfaces. Transmission lines.
For students without a background in physics, it is suggested to follow the course ELECTROMAGNETIC MATERIALS of Prof. Genovesi.
Face to face lectures with slides and Matlab laboratory sessions to fix the most important concepts with practical implementations.
PROPERTIES OF MATERIALS: General properties of materials, polarization phenomena, propagation through dispersive materials, properties of conductors (surface impedance), dispersion models (Lorentz, Debye, Drude), Discrete Fourier Transform.
CHARACTERIZATION OF MATERIALS and SENSORS: Surface Plasmoons and applications. Methods for retrieving the dielectric, magnetic properties of materials in the microwave range including laboratory demonstrations. Wireless radio frequency sensors for Non Destructive Testing (NDT).
PERIODIC STRUTURES: Theory of periodic structures, dispersion diagram of 2D periodic structures, Fouquet theorem, Photonic Crystals, Frequency Selective Surfaces, .
Download the slides from elearn.ing.unipi.it and repeat the laboratory exercises on matlab. Ask the teacher for a project well before oral examination.
Development of a project, preparation of a technical note and a ppt presentation. Discussion on the project during the oral exam and addtional questions on the program.
