227-0085-01L	Projects & Seminars: Amateur Radio Course Does not take place this semester. Only for Electrical Engineering and Information Technology BSc. The course unit can only be taken once. Repeated enrollment in a later semester is not creditable.	1.5 credits	1P	J. Leuthold
Abstract	The category of "Laboratory Courses, Projects, Seminars" includes courses and laboratories in various formats designed to impart practical knowledge and skills. Moreover, these classes encourage independent experimentation and design, allow for explorative learning and teach the methodology of project work.
Learning objective	"Amateur radio" enables wireless communicate over long distances. However, an amateur radio station may not be operated without further ado of an official license. To operate an amateur radio one needs to pass the HB3 or HB9 examination offered by the federal office of communication (OFCOM). In this course we will cover the most important topics of amateur radio. There willl also be a practical part. In this part you will have the opportunity to take the radio into your own hands. For example, you will be offered the opportunity during a “portable” excursion (not subject to testing) to set up and operate a mobile radio station in the field. Although the course prepares for the OFCOM exam, the exam itself is not a prerequisite for obtaining the P&S credits. The HB9 exam by the OFCOM will be offered after the course, and it will only be offered to those that actively participate in the course. As part of the exam it will be e.g. necessary to successfully set up a radio connection to another station. Upon a successful exam one may use the AMIV radio shack on the roof of the ETZ or set up and operate the own system. The learning material will be handed out in the first lesson of the course.
227-0085-03L	Projects & Seminars: COMSOL Design Tool – Design of Optical Components Only for Electrical Engineering and Information Technology BSc. The course unit can only be taken once. Repeated enrollment in a later semester is not creditable.	3 credits	3P	J. Leuthold
Abstract	The category of "Laboratory Courses, Projects, Seminars" includes courses and laboratories in various formats designed to impart practical knowledge and skills. Moreover, these classes encourage independent experimentation and design, allow for explorative learning and teach the methodology of project work.
Learning objective	Simulation tools are becoming an essential accessory for scientists and engineers for the development of new devices and study of physical phenomena. More and more disciplines rely on accurate simulation tools to get insight and also to accurately design novel devices. COMSOL is a powerful multiphysics simulation tool. It is used for a wide range of fields, including electromagnetics, semiconductors, thermodynamics and mechanics. In this P&S we will focus on the rapidly growing field of integrated photonics. During hands-on exercises, you will learn how to accurately model and simulate various optical devices, which enables high-speed optical communication. At the end of the course, students will gain practical experience in simulating photonic components by picking a small project in which certain photonic devices will be optimized to achieve required specifications. These simulated devices find applications in Photonic Integrated Circuits (PICs) on chip-scale. Course website: https://blogs.ethz.ch/ps_comsol
Prerequisites / Notice	No previous knowledge of simulation tools is required. A basic understanding of electromagnetics is helpful but not mandatory. The course will be taught in English.
227-0085-32L	Projects & Seminars: Magnetic Fields in Our Daily Life Does not take place this semester. Only for Electrical Engineering and Information Technology BSc. The course unit can only be taken once. Repeated enrollment in a later semester is not creditable.	2 credits	2P	J. Leuthold
Abstract	The category of "Laboratory Courses, Projects, Seminars" includes courses and laboratories in various formats designed to impart practical knowledge and skills. Moreover, these classes encourage independent experimentation and design, allow for explorative learning and teach the methodology of project work.
Learning objective	Magnetic fields can be found everywhere but are rarely directly perceptible. This also leads to sometimes irrational fears, such as of electrosmog. The power supply with direct current, 16.67 Hz and 50 Hz alternating current is indispensable today. Wherever electricity flows, magnetic fields are generated. That is why magnetic fields are omnipresent. But where do particularly high fields occur? How high can these fields be before they cause damage to health? Many studies have already dealt with this question and country-specific guidelines have been defined on this basis. But are these actually adhered to? Where are the legal limits exceeded? What are the consequences? The P&S will deal with this topic and an invited guest will speak. The participants of the P&S will pursue small research projects of their own. To do this, they will be equipped with mobile measuring devices that can be connected to a smartphone to search for and characterise various magnetic field sources. How strong are the magnetic fields in our environment really? Can they pose a danger? How can they be shielded? These questions will be systematically investigated. At the end of the P&S, the individual groups present the findings
227-0085-54L	Projects & Seminars: Optics and Spectroscopy Lab Only for Electrical Engineering and Information Technology BSc. Course can only be registered for once. A repeatedly registration in a later semester is not chargeable.	3 credits	4P	J. Leuthold
Abstract	The category of "Laboratory Courses, Projects, Seminars" includes courses and laboratories in various formats designed to impart practical knowledge and skills. Moreover, these classes encourage independent experimentation and design, allow for explorative learning and teach the methodology of project work.
Learning objective	The goal of this P&S is to learn the basics of working with optics and how to assemble optical systems. It is intended to show the practical side to the many optics lectures that are offered at D-ITET. The course will give a very brief introduction on laser safety, basic building blocks for optics and information on how to handle such elements. The following classes allow the students to test very basics properties of lenses and lasers and how the corresponding optomechanics can be used to arrange a simple setup. After this, the different student groups rotate through four different experiments where they get the chance to build and align different optical setups and perform various measurements. No prior knowledge is required.

Learning objective	How strong is the electromagnetic radiation generated by base stations, mobile phones and TV towers? What can you do in order to minimize your daily exposure to electromagnetic fields? In this project you will learn the basic know-how required to deal and work with radio frequency electromagnetic fields. You will see our microwave laboratory and get familiar with the RF and microwave measurement equipment. Using ExpoM-RF, a personal exposure meter originally developed at the Institute of Electromagnetic Fields, you will be able to perform outdoor measurements and track your daily exposure to electromagnetic fields in the frequency range from 87.5 MHz to 5.8 GHz.
