	Objectives
	THE COURSE “ADVANCED ELECTROMAGNETIC” REPRESENTS THE NATURAL COMPLETION OF THE TOPICS TACKLED IN THE PREVIOUS ELECTROMAGNETICS COURSES AND, IN PARTICULAR, IN THE ANTENNAS ONE. TO THIS END, SOME NUMERICAL AND ANALYTICAL TECHNIQUES, WIDELY EMPLOYED TO SOLVE ELECTROMAGNETIC PROBLEMS, ARE PRESENTED. THE COURSE CONTAINS A SIGNIFICANT PART FOCUSED ON LEARNING THE USE OF A CAD-SOFTWARE BASED ON THE FINITE ELEMENT METHOD.

	Prerequisites
	A GOOD KNOWLEDGE OF THE TOPICS TACKLED IN THE PREVIOUS ELECTROMAGNETICS COURSES AND, IN PARTICULAR, OF THE ANTENNAS THEORY IS MANDATORY TO PROFITABLY REACH THE GOAL OF THE COURSE.

	Contents
	REVIEW OF THE FUNDAMENTAL LAWS OF ELECTROMAGNETICS. CLASSIFICATION OF ELECTROMAGNETIC (EM) PROBLEMS. FINITE DIFFERENCE METHOD (FD) AND ITS APPLICATION TO THE SOLUTION OF EM PROBLEMS. ACCURACY AND STABILITY OF FD SOLUTIONS. (3 hours teaching time - 2 hourS interactive classroom activities with exercises) THE FINITE ELEMENT METHOD (FEM): DISCRETIZATION OF DOMAIN IN FINITE ELEMENTS: MESHING A VOLUME (GENERATION OF AN ADAPTATIVE MESH), ELEMENT GOVERNING EQUATIONS, MODELING A SOURCE, ASSEMBLING OF ALL ELEMENTS AND SOLVING THE RESULTING SYSTEM OF EQUATIONS. BOUNDARY CONDITIONS: “PERFECTLY MATCHED LAYER” (PML), “ANISOTROPIC UNIAXIAL PML” (U-PML), "RADIATION BOUNDARY", "MASTER-SLAVE" BOUNDARY CONDITION FOR INFINITE PERIODIC STRUCTURES (FSS). (3 hours teaching time - 8 hours interactive classroom activities with exercises) DECRIPTION OF SOME SOFTWARE TOOLS WIDELY EMPLOYED IN ELECTROMAGNETICS. NUMERICAL FEM CODE DEVELOPMENT TO ANALYZE A PLANAR SPIRAL ANTENNA TO FUNCTION AS A RFID-TAG. (3 hours teaching time - 8 hourS interactive classroom activities with exercises) ASYMPTOTIC EVALUATION OF ONE-DIMENSIONAL AND TWO-DIMENSIONAL INTEGRALS BY MEANS OF THE STATIONARY PHASE METHOD. UNIFORM ASYMPTOTIC EVALUATION BY MEANS OF THE STEEPEST DESCENT METHOD OF AN INTEGRAL WITH ONE OR MORE POLE SINGULARITIES NEARBY A FIRST ORDER SADDLE POINT. APPLICATION TO THE EVALUATION OF THE UNIFORM DIFFRACTION COEFFICIENTS FOR A LOADED WEDGE. (Hours: 8 theory - 2 exercises) SOLUTION OF HELMOLTZ SCALAR EQUATION IN CYLINDRICAL COOORDINATES. CYLINDRICAL WAVE EXPANSION OF THE FIELD RADIATED BY AN ANTENNA. CYLINDRICAL NEAR-FIELD-FAR-FIELD TRANSFORMATION (NF-FF) WITH AND WITHOUT PROBE COMPENSATION. (Hours: 7 theory - 2 exercises) NONREDUNDANT SAMPLING REPRESENTATIONS OF ELECTROMAGNETIC FIELDS: REDUCED FIELD AND LOCAL (SPATIAL) BANDWIDTH, OPTIMAL CHOICE OF THE PHASE FACTOR AND PARAMETERIZATION. ELLIPSOIDAL MODELLINGS OF THE RADIATING SOURCE. OPTIMAL INTERPOLATION OF THE ELECTROMAGNETIC FIELD ON ROTATIONAL SURFACES. APPLICATION OF THE NONREDUNDANT SAMPLING REPRESENTATIONS TO THE NF-FF TRANSFORMATIONS WITH CYLINDRICAL, PLANE-POLAR, BI-POLAR, AND SPHERICAL SCANNINGS. NF-FF TRANSFORMATION TECHNIQUES WITH SPIRAL SCANNINGS. (Hours: 8 theory - 4 exercises - 2 laboratory)

	Teaching Methods
	THE COURSE MAINLY INCLUDES THEORETICAL LESSONS, BUT THERE ARE ALSO MANY NUMERICAL AND SOME LABORATORY PRACTICES. THE NUMERICAL ONES ARE CONCERNED WITH THE USE OF SOFTWARE TOOLS WIDELY EMPLOYED TO SOLVE ELECTROMAGNETIC PROBLEMS BOTH IN THE SCIENTIFIC RESEARCH AND IN THE INDUSTRIAL DESIGN. SOME COMPUTER CODES BASED ON THE STUDIED TECHNIQUES ARE ALSO DESCRIBED. THE LABORATORY PRACTICES DEAL WITH ADVANCED ELECTROMAGNETIC MEASUREMENTS. AS, E.G., THE DETERMINATION OF THE ANTENNA RADIATION PATTERN FROM NONREDUNDANT NEAR-FIELD MEASUREMENTS ACQUIRED VIA A SPIRAL SCANNING. IT IS ALSO PLANNED THE DESIGN (IN GROUP) OF AN ANTENNA, THE EXPERIMENTAL VERIFICATION OF ITS RADIATION PATTERN, AND THE WRITING OF THE RELATED TECHNICAL REPORT.

	Verification of learning
	AN ORAL EXAMINATION WILL VERIFY THE REACHING OF THE FIXED GOALS. THE STUDENT CAN SPLIT THE EXAMINATION INTO FOUR PARTS. IN SUCH A CASE, THE OVERALL EVALUATION WILL PROPERLY TAKE INTO ACCOUNT THE RESULTS OBTAINED IN THE PREVIOUS TESTS AND IN THE FINAL ONE.
