The objectives of this course are to understand and gain the complete knowledge on the main microwave components and to design the microwave networks realized by combining them. Microwave and millimeter-wave systems for different application, such as radars, satellite and wireless communications, are presented and discussed. The course has also the objective to provide the knowledge on the advanced microwave components based on metamaterials and metasurfaces. The design of the microwave components and networks can be supported by professional CAD software, that are presented during the course.

Type of delivery of the course
The course consists of front lessons, exercises, and simulations with PC. It is recommended (not mandatory) to have a PC for analyzing, designing and simulating the microwave networks and circuits presented during the course.Type of evaluation
The final exam consists of a written test consisting of two parts: PART 1: written presentation and discussion of a topic of the course (the topic is selected by the student among two topics provided by the examination commission). It is 1/3 of the entire exam. PART 2: design of a microwave networks that satisfies the specifications reported in the test (it is possible to see the textbooks and notes). It is 2/3 of the entire exam. The written test is finalized to check the knowledge of the student on the main concepts of the course and to verify its ability to apply them in realistic scenarios.
