Course aims:

- Assimilation by students of the physical sizes and fundamental laws that govern the phenomena of nature on a macroscopic scale with the purpose of basic intellectual training of the future electronic engineer;
- Training students to understand the problems of applicative nature in the technical fields from the point of view of the fundamental legalities of nature;
- Developing creative technical thinking by understanding and handling the concepts of physics that underlie modern measuring materials and devices.
- Development of students' ability to operate with the concepts of mechanical physics, electricity and optics using the mathematical apparatus specific to the university level (functions of several variables, complex functions, differential operators, etc.);
- Initiation of future engineers in the development and use of physical models, as a practical way of extracting the essentials from a complex set of empirical phenomena;

Presentation, debate, lecture. Course and seminar materials, experimental laboratory stand or video materials without restrictions of use for didactic / educational purposes.

Learning outcomes:

The course presents in a unitary conception, notions regarding the object of the science and engineering of materials, with the purpose of generating and applying the knowledge regarding the composition, structure and processing of materials for electronics. The course focuses on the nature of the materials, presenting the theories that explain the relationship; structure - processing - property - performance (operating behavior).

Learning outcomes verification and assessment criteria:

Written evaluation 50%, Check in progress 20%, Performing laboratory workPerforming laboratory work 30%
