Objectives
The aim of the Photonics in Materials discipline is to teach the basic concepts of the field of applied physics related with light-matter interaction. The discipline introduces the students to the areas of electromagnetism, quantum mechanics and solid state physics, so that they gain fundamental knowledge in such domains that will later be developed in subsequent disciplines of the course.
The discipline will have a strong applied character, since all lectured topics will be presented in the context of current research and technological development. The laboratory work will highly contribute in that respect, since it will allow the students to follow a real experiment in nanophotonics and execute the inherent steps of fabrication, characterization and results interpretation.

Teaching method
The discipline will be mainly composed of theoretical-practical lessons and some laboratory work, which will contain oral discussion with and between the students.
Evaluation method
Avaliação Teórico-Pratica (90%):
- 3 tests or exam
Grade = average between the tests or exam grade
Minimum average grade between tests = 9.5
Avaliação Sumativa (10%):
- Participation and problem solving in class (each exercise graded on a scale of 0-4)
- Performance and quiz solving in laboratory lessons
No minimum graded required for the Avaliação Sumativa.
