Prerequisites:
|
Fundamentals of electromagnetics (e.g., as taught in the course of "Physics II"). |
Target skills and knowledge:
|
This course explores the fundamentals of light-matter interaction and photonics phenomena. The course will also provide an introduction to practical photonic components and systems and provide an overview of applications of photonics in sensor systems dedicated to agrifood, environmental monitoring and biosensing. |
Examination methods:
|
Oral exam. |
Assessment criteria:
|
Knowledge of theory and the understanding of the applicative aspects of the discipline. Ability to apply the theoretical concepts to concrete cases. Ability to expose the concepts through appropriate terminology. |
Course unit contents:
|
