Evaluation

16

• Each student reviews one specific area of plasmonics and gives an oral presentation.

25 min. presentation + 10 min. Q&A

• The topic categories will be listed on the course webpage, but you are welcome to propose one. (Max. 3 person per category)

• For each presentation, students should ask at least one question.

• Each student evaluates the other students’ presentation.

• Final score = Students (50%) + Instructor (50%)

Final paper presentation:
