AIMS AND CONTENT

LEARNING OUTCOMES

The purpose of the module is to teach the fundamental methods of rapidly variable electromagnetic field analysis using a differential approach, and then to move on to the acquisition of issues related to industrial electromagnetic compatibility with reference to design and measurement method issues.

AIMS AND LEARNING OUTCOMES

In the EMC module, initially, a first preparatory part is carried out aimed at acquiring the cultural mastery of Maxwell's equations in differential form, of rapidly variable fields and of the propagation phenomena of electromagnetic waves.

The second part of the course aims to deepen the issues related to industrial electromagnetic compatibility with particular reference to both design with electromagnetic compatibility constraints and problems related to measurement methods

Upon completion of the course, students will have acquired the skills necessary to meet the challenges of EMC in the industrial sector, helping to improve the reliability and safety of electrical and electronic systems

TEACHING METHODS

The course will consist of theoretical lectures, practical examples and laboratory sessions, offering comprehensive and practical training. Visits to companies will also be carried out.

"Students with valid certifications for Specific Learning Disorders (SLDs), disabilities or other educational needs are invited to contact the teacher and the School's contact person for disability at the beginning of teaching to agree on possible teaching arrangements that, while respecting the teaching objectives, take into account individual learning patterns. Contacts of the teacher and the School's disability contact person can be found at the following link Comitato di Ateneo per l’inclusione delle studentesse e degli studenti con disabilità o con DSA | UniGe | Università di Genova"
