Objectives
AIM OF THE COURSE IS TO SUPPLY STUDENTS WITH BASE KNOWLEDGE’S ABOUT ELECTROMAGNETIC WAVES AND TO INTRODUCE THEM TO THE METHODOLOGY FOR THEIR QUANTITATIVE ANALYSIS. IN PARTICULAR, THE COURSE DEALS WITH THE PROPAGATION MECHANISMS OF ELECTROMAGNETIC WAVES AND THE PROPAGATION OF ELECTROMAGNETIC WAVES IN GUIDING STRUCTURES SUCH AS TRANSMISSION LINES.

KNOWLEDGE AND UNDERSTANDING
AT THE END OF THE COURSE THE STUDENT, IN HIS CULTURAL BAGGAGE, HAS:
-THE KNOWLEDGE OF THE FUNDAMENTAL THEOREMS OF ELECTROMAGNETICS
-THE METHODOLOGICAL KNOWLEDGE NECESSARY TO TACKLE AND SOLVE ELECTROMAGNETIC WAVE PROPAGATION PROBLEMS, WITH AN UNDERSTANDING OF THE RELATED PHYSICAL PHENOMENA;
-THE ABILITY TO SOLVE THROUGH THE CIRCUIT APPROACH PROBLEMS INVOLVING THE PROPAGATION OF AN ELECTROMAGNETIC SIGNAL ALONG A TRANSMISSION LINE.
APPLIED KNOWLEDGE AND UNDERSTANDING
AT THE END OF THE COURSE THE STUDENT HAS DEVELOPED A SOLID KNOWLEDGE OF THE SCIENTIFIC-METHODOLOGICAL ASPECTS NECESSARY TO CHARACTERIZE THE PROPAGATION OF ELECTROMAGNETIC WAVES AND IS ABLE:
-TO SOLVE THE PROBLEM OF THE PROPAGATION OF ELECTROMAGNETIC FIELDS IN LAYERED MEDIA;
-TO ANALYZE THE BEHAVIOR OF VOLTAGE AND CURRENT ALONG A TRANSMISSION LINE;


PERSONAL JUDGMENTS
THE STUDENT IS ABLE:
-TO DISCRIMINATE THE PROPAGATING MECHANISMS OF THE ELECTROMAGNETIC FIELD;
-TO ANALYZE A CIRCUIT CONSISTING OF A CASCADE OF TRANSMISSION LINES LINKING A GENERATOR CIRCUIT TO THE CORRESPONDING LOAD.

ABILITÀ COMUNICATIVE:
-LO STUDENTE DOVRÀ ESSERE IN GRADO DI ESPORRE CON LINGUAGGIO TECNICO ADEGUATO LE PROBLEMATICHE CONNESSE AGLI ASPETTI PROPAGATIVI DEL CAMPO ELETTROMAGNETICO.

COMMUNICATION SKILLS
BEING ABLE TO EXPOSE, IN A CLEAR AND CONCISE WAY, THE ISSUES RELATED TO THE PROPAGATION 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.
Prerequisites
FOR THE SUCCESSFUL ACHIEVEMENT OF THE OBJECTIVES, A SUITABLE KNOWLEDGE OF MATHEMATICS AND PHYSICS IS REQUIRED. Mathematics III and Physic II.

Teaching Methods
THE COURSE, TAUGHT IN ITALIAN, INCLUDES THEORETICAL LESSONS AND CLASSROOM EXERCISES ON THE TOPICS PROPOSED DURING THE THEORETICAL LESSONS.
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 SIGNAL PROPAGATION IN DYNAMIC REGIME, THE PROPAGATION MECHANISMS OF ELECTROMAGNETIC WAVES AND ON THE CIRCUIT APPROACH TO DESCRIBE THE WAVE PROPAGATION ALONG TRANSMISSION LINES 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.
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 ARGUE WHAT IS REQUIRED.

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 (PROPAGATION OF AN ELECTROMAGNETIC WAVE IN FREE SPACE AND ITS INTERACTION WITH MATERIALS OF DIFFERENT CHARACTERISTICS OR PROPAGATION OF AN ELECTROMAGNETIC SIGNAL ALONG A TRANSMISSION LINE).
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 AND ITS INTERACTION WITH MATERIALS OF DIFFERENT CHARACTERISTICS OR PROPAGATION OF AN ELECTROMAGNETIC SIGNAL ALONG A TRANSMISSION LINE.

MOREOVER, 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 POSSIBLE, WITH THOSE OF OTHER DISCIPLINES;
- THE DEMONSTRATED PERSONAL JUDGMENT.
