This course, dealing with topics of scientific-technological interest such as electromagnetic fields, contributes to the achievement of the following Sustainable Development Goals of the UN 2030 Agenda:
8.2 (Achieving higher standards of economic productivity through diversification, technological progress and innovation, also with particular attention to high added value and labor intensive sectors)
9.5 (Increase scientific research, improve the technological capabilities of the industrial sector in all states - especially in developing countries - as well as encourage innovations and substantially increase, by 2030, the number of employees for every million people, in the research and development sector and expenditure on research – both public and private – and on development)
