Objective | Der Amateurfunk ermöglicht es, drahtlos über weite Distanzen zu kommunizieren. Doch darf eine Amateurfunk-Station nicht ohne Weiteres betrieben werden. Voraussetzung ist das Ablegen der Amateurfunkprüfung HB3 oder HB9 beim BAKOM. In diesem Kurs werden wir einen Überblick über die wichtigsten Themengebiete des Amateurfunks bieten. Im praktischen Teil werdet ihr unter anderem die Gelegenheit haben, das Funkgerät selbst in die Hand zu nehmen. In einem Portabel-Ausflug (nicht testatpflichtig) werden wir zudem draussen eine mobile Funkstation aufbauen und bedienen. Nach dem Kurs habt ihr die Möglichkeit, die HB9-Prüfung abzulegen. Mit der Prüfung in der Tasche könnt ihr dann auch die Funkbude des AMIV auf dem ETZ-Dach verwenden oder auch eure eigene Anlage aufbauen und betreiben. Voraussetzung für das Testat ist eine aktive Teilnahme am Kurs, nicht das Bestehen der BAKOM-Prüfung. Eine erfolgreiche Funkverbindung zu einer anderen Station ist ebenfalls Teil der Testatbedingung. Das Lernmaterial wird in der ersten Kursstunde ausgegeben. | ||||

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. | ||||

Objective | Python is an interpreted high-level programming language which is becoming increasingly popular in the academic scientific community as well as in industry. The course will introduce the basics of the python programming language, and will cover some of the most useful Python modules, such as numpy, scipy and matplotlib. The classes will further cover simple GUIs, data analysis and linking with shared libraries or C code. They will further familiarize with the GIT version control system, with the linux shell and with the most common software licenses. Students are not required to have previous Python programming experience. | ||||

Objective | Magnetfelder sind überall zu finden aber selten direkt wahrnehmbar. Das führt auch zu teils irrationalen Ängsten wie beispielsweise vor Elektrosmog. Die Stromversorgung mit Gleichstrom, 16.67 Hz und 50 Hz Wechselstrom ist heute nicht mehr wegzudenken. Überall wo Strom fliesst, entstehen auch Magnetfelder. Deswegen sind Magnetfelder allgegenwärtig. Aber wo treten besonders hohe Felder auf? Wie hoch dürfen diese sein bevor gesundheitliche Schäden entstehen können? Damit haben sich schon viele Studien befasst und darauf basierend wurden landesspezifische Richtlinien definiert. Doch werden diese überhaupt eingehalten? Wo werden die gesetzlichen Grenzwerte überschritten? Was sind die Konsequenzen? Mit diesem Thema befasst sich das P&S und spricht ein eingeladener Gast. Die Teilnehmer des P&S werden kleine eigene Forschungsprojekte verfolgen. Dafür werden sie mobilen Messgeräten ausgerüstet, welches sich mit einem Smartphone verbinden lassen, um verschiedene Magnetfeldquellen zu suchen und zu charakterisieren. Wie stark sind die Magnetfelder in unserem Umfeld wirklich? Können sie eine Gefahr darstellen? Wie können sie abgeschirmt werden? Diese Fragen sollen systematisch untersucht werden. Zum Abschluss des P&S präsentieren die einzelnen Gruppen die Erkenntnisse aus ihren Messungen fassen diese in einem kurzen Bericht zusammen. | ||||
