APPLIED KNOWLEDGE AND UNDERSTANDING AT THE END OF THE COURSE THE STUDENT IS ABLE: TO SOLVE A SIMPLE MICROWAVE CIRCUIT AND TO DESIGN THE RELATED MATCHING NETWORK; TO ANALYZE, ALSO WITH THE AID OF DEDICATED SOFTWARE, THE PROPAGATION OF ELECTROMAGNETIC WAVES IN A GUIDING STRUCTURE ACCORDING TO ITS GEOMETRY AND ITS TRANSVERSE DIMENSIONS; TO CHOOSE, BASED ON THE SPECIFICATIONS, THE ANTENNAS TO DESIGN A RADIO LINK OR A RADIOMOBILE COVERAGE. PERSONAL JUDGMENTS THE STUDENT IS ABLE: TO DISCRIMINATE THE PROPAGATING MECHANISMS OF THE ELECTROMAGNETIC FIELD AND THE PARAMETERS DESCRIBING THE RADIATION CHARACTERISTICS OF AN ANTENNA BOTH IN TRANSMISSION AND RECEPTION; TO ANALYZE A MICROWAVE CIRCUIT. COMMUNICATION SKILLS BEING ABLE TO EXPOSE, IN A CLEAR AND CONCISE WAY, THE ISSUES RELATED TO THE PROPAGATION AND RADIATION ASPECTS OF THE ELECTROMAGNETIC FIELD, BY MAKING USE OF AN ADEQUATE TECHNICAL TERMINOLOGY AND OF THE TOOLS OF THE MATHEMATICAL AND GRAPHIC REPRESENTATION OF THE PHENOMENA EXPOSED. LEARNING SKILLS BEING ABLE TO APPLY THE ACQUIRED KNOWLEDGE TO DIFFERENT CONTEXTS FROM THOSE PRESENTED DURING THE COURSE; BEING ABLE TO DEEPEN THE TOPICS USING MATERIALS OTHER THAN THOSE PROPOSED FOR THE COURSE.

	Teaching Methods
	THE COURSE INCLUDES THEORETICAL LESSONS AND CLASSROOM EXERCISES ON THE TOPICS PROPOSED DURING THE THEORETICAL LESSONS. DURING THE COURSE, WILL BE AVAILABLE FOR EACH STUDENT THE HFSS ANSYS SOFTWARE FOR THE NUMERICAL CHECK OF THE STUDIED THEORETICAL TOPICS AND FOR THE ACQUISITION OF THE CAD SKILLS IN THE DESIGN PROCESS. DURING THE LESSONS THE TOPICS COVERED ARE PRESENTED WITH GRADUALLY INCREASING THEIR COMPLEXITY. IN THE EXERCISES, THE STUDENT IS ASKED TO SOLVE PROBLEMS RELATED TO THE TOPICS COVERED IN THE THEORETICAL LESSONS. THE RESOLUTION METHOD CONSISTS OF UNDERSTANDING THE PROBLEM, PLANNING THE SOLUTION, AND FINALLY THE RESOLUTION ITSELF. DURING THIS LAST STEP, THE HABIT OF EVALUATING THE REASONABLENESS OF THE RESPONSE AND VERIFYING ITS CONSISTENCY IS PROMOTED.

	Verification of learning
	THE DEGREE OF LEARNING OF THE STUDENT ON THE FUNDAMENTAL PRINCIPLES OF ELECTROMAGNETIC FIELD PROPAGATION IS ASSESSED BY AN ORAL EXAM OF AN AVERAGE DURATION OF 45 MINUTES. THE EVALUATION GRADE, RANGING FROM 18/30 TO 30/30 CUM LAUDE, WILL DEPEND ON THE MATURITY ACQUIRED BY THE STUDENT ON THE COURSE CONTENTS. DURING THE COURSE IT IS POSSIBLE TO PERFORM TWO PARTIAL EXONERATIVE TESTS, RESPECTIVELY AFTER ONE HALF OF THE LESSONS AND AT THE END OF THE COURSE. EACH TEST WILL WEIGH 50% ON THE FINAL EVALUATION AND THE FINAL EVALUATION GRADE WILL BE GIVEN BY THE WEIGHTED AVERAGE OF THE TWO TESTS. IN PARTICULAR, THE EXAM AIMS: TO VERIFY THE LEARNING OF THE TOPICS COVERED IN THE THEORETICAL LESSONS; TO VERIFY THE ABILITY TO EXPOSE THE COVERED TOPICS; TO VERIFY THE PERSONAL JUDGMENT IN PROPOSING THE MOST APPROPRIATE APPROACH TO ANSWER. TO PASS THE EXAM (MINIMUM GRADE 18), IT IS NECESSARY TO DEMONSTRATE TO HAVE ACHIEVED A SUFFICIENT GRADE OF LEARNING OF THE TOPICS COVERED IN THE THEORETICAL LESSONS AND, EVENTUALLY, TO BE ABLE TO SOLVE A PROPOSED ELECTROMAGNETIC PROBLEM (IN THE FREE SPACE OR IN A GUIDED STRUCTURE). THE MAXIMUM GRADE (30/30) IS ATTRIBUTED WHEN THE STUDENT DEMONSTRATES A COMPLETE AND IN-DEPTH KNOWLEDGE OF THE VARIOUS TOPICS COVERED IN THE THEORETICAL LESSONS AND IS ABLE TO SOLVE ELEGANTLY AN ELECTROMAGNETIC PROBLEM IN THE FREE SPACE OR IN A GUIDED STRUCTURE, TO ANALYSE A MICROWAVE CIRCUIT AND TO OUTLINE A DESIGN OF A RADIO LINK MOREOVER, IN ORDER TO TO BE AWARDED CUM LAUDE, IT WILL BE TAKEN INTO ACCOUNT: THE QUALITY OF ORAL EXPOSITION, IN TERMS OF THE USE OF AN APPROPRIATE SCIENTIFIC LANGUAGE; THE ABILITY OF CROSS-CORRELATION BETWEEN THE DIFFERENT TOPICS OF THE COURSE AND, WHEN IT IS POSSIBLE, WITH THOSE OF OTHER DISCIPLINES; THE DEMONSTRATED PERSONAL JUDGMENT.
