Ab 2. November 2020 findet das Herbstsemester 2020 online statt. Ausnahmen: Veranstaltungen, die nur mit Präsenz vor Ort durchführbar sind. Bitte beachten Sie die per E-Mail kommunizierten Informationen der Dozierenden.
This course reviews current research topics in Terahertz Science with a strong focus on scientific applications in physics, chemistry and biology, as well as the emerging field of nonlinear THz optics.
Terahertz frequency electromagnetic radiation lies at the border between electronics and optics, and as such has many unique properties that make it well-suited to study the electronic, magnetic and structural properties of many materials. The course objective is to give students the ability to identify problems of current interest in physics, chemistry, materials science and biology that can be potentially addressed using terahertz photonics and to design potential experimental solutions.
The course will focus predominantly on understanding research conducted over the last 4-5 years at the forefront of this developing field, with a strong emphasis on nonlinear THz science which has only recently become possible. This in particular has generated excitement as it offers potential new ways to control chemical reactions and/or phase transitons in materials.
Topics to be discussed in the class include:
1) Overview of THz & interactions with matter 2) THz generation and detection 3) Linear THz spectroscopies 4) Imaging 5) Nonlinear THz interactions
Scripts will be distributed via moodle.
The readings for the course will draw mostly on current journal articles that will be distributed in class/via moodle. There is also a general textbook listed below available electronically via the ETH library system. You can also order a black-and-white paperback via an "on-demand" system for a pretty reasonable price.
