Teaching methods
In the classroom lectures (with slides projection) the analysis and basic design methods of the main nonlinear blocks of modern transceivers are treated,with special emphasis to Wireless Power Transfer applications. Practical examples and prototypes are described/shown in class for a deep understanding of recent wireless and energy-aware solutions. The training hours are devoted to the design/development of application examples.
Assessment methods
Oral exam consisting in a discussion aimed at establishing the student's understanding of the treated principles, methodologies, and laboratory experiments as well as of his/her ability to apply them to practical engineering problems
Teaching tools
Projection of slides, blackboard, and circuit prototypes
