Learning outcomes
KNOWLEDGE AND UNDERSTANDING:
Knowledge of the circuit representation of a device: definition of ports. Definition and propertied of matrices modelling linear devices. Comparative analysis of waveguides. Features of linear reciprocal devices featuring 2, 3 and 4 ports. Non reciprocal devices with 2 and 3 ports.
CAPACITY TO APPLY KNOWLEDGE AND UNDERSTANDING:
Being able to choose  waveguides in order to realize certain a connection, as a tradeoff between costs, performance and power needs.  Being able to design adapters,  filters,  diplexers,  directional couplers. Ability of comparing different microwave devices. Ability of measuring the scattering matrix of a linear multiport by a Vector Network Analyzer.
TRANSVERSAL SKILLS:
The study of Microwaves requires the student to exploit methods and notions acquired from basic lectures, in particular Physics, Electromagnetic Fields, Calculus, Linear Algebra, as well as Circuit Theory and Signal Theory. Indeed, it is a multidisciplinary activity, deeply stimulating the synthesis ability,  which is a paradigm of the way an engineer faces real problems.

Program
Properties of transmission lines: microstrips and striplines. Linear junctions and their matrices. Physical realizability. Losslessness, reciprocity and simmetry. Bandwidth. Two port junctions: adapters, filters, isolators and phase shifters. Three-port junctions. Symmetry. Y and T junctions. Diplexers. Coupled lines. Directional couplers. Network Analyzer.

Development of the examination
LEARNING EVALUATION METHODS
Oral examination. The test consists of two questions among the main topics of the course.

LEARNING EVALUATION CRITERIA
The exam is aimed at evaluating the candidate's skill in the subject, according to the following parameters: knowlegde, understanding, implementation, presentation.

LEARNING MEASUREMENT CRITERIA
The purpose of the examination is to assess the candidate's skill. There are three reference levels: base - acquistion of procedures for the solution of canonical problems, as those of the written test. Oral presentation sufficient with a few uncertainesses in the usage of specific language.intermediate - ability to apply the above procedures to problems not obviously related to canonical problems. Oral part presented correcly and in proper order. top - ability of exploiting models and developing strategies requiring the combination of procedures for solving non familiar problems. Oral presentation clear, logical and appropriate.

FINAL MARK ALLOCATION CRITERIA
The mark is allocated on the basis of the acquired knowledge. A score ranging from 18/30 and 23/30 is attributed to the level 'base', a score ranging from 24/30 to 27/30 to the intermediate level, and a score between 28/30 and 30/30 to the top level. A candidate is awarded cum laude when they are able to deal even with new problems in a fully autonomous way.
