Harmonic oscillator, both free and forced; coupled oscillators. Wave equation, elastic waves in solids, liquids, gases. E.m. waves: propagation in vacuum, in dielectric and in conducting media, polarization, reflexion, refraction, dispersion. Wave optics, Huyghens principle, interference, Fraunhofer and Fresnel diffraction. Interferometers: Michelson, Mach-Zender, Fabry-Perot; interference of thin filmes, coatings. Photomery.
Gauss approximation for paraxial beams, geometrical optics: diopter, mirror, lens, optical system and lens luminosity, human eye
Aim of this course is to provide students with additional training on the topic of waves, both elastic and electromagnetic, and basic training on both wave and geometrical optics. Finally, an introduction on wave guides and on propagation of e.m. waves in solids.
KNOWLEDGE AND UNDERSTANDING:
Students will be able, at the end of the course, to show they handle with familiarity the basic concepts of wave optics, to analyze an optical system and to know the basics of radiation transmission in solids, including anisotropy.
APPLYING KNOWLEDGE AND UNDERSTANDING:
The notions and methods acquired in this course will support the students in the following of their progression along the program of Material Science degree. They will enable students to understanding of optical measurements and optical properties of materials.
Students that pass the final exam will be able to independently orient themselves in the field of optical instruments and measurements and to design simple test devices.
Students will acquire the specific lexicon of optical experiments. The final exam will consists of both a written and an oral test: in the latter, the student will be able to show her/his in communication and exposition ability. It is also under consideration the hypothesis of asking each student a brief presentation to the class on a special topic.
At the end of the course, the students will be able to independently read a scientific text describing an optical apparatus of medium complexity.
