Kursspecifika förkunskaper

Basic knowledge in radio and microwave engineering.

Syfte

This course aims to introduce students to the problems of guiding, detecting and generating electromagnetic radiation at millimeter wavelengths (MM-waves) and at Terahertz frequencies. Through the course, students will receive lectures on the subjects outlined above and will additionally perform laboratory work to acquire practical skills. A project work guided by teachers will focus students' studies on a deeper understanding of a selected problem within the course subject. The course goal is to provide students with a wide introduction to millimeter and sub-millimeter (Terahertz) technology for industrial applications, instrumentation in radio astronomy, environmental science and other applications.

Lärandemål (efter fullgjord kurs ska studenten kunna)

- understand principals of building and methods of characterization of low-noise receivers for millimeter and Terahertz bands;
- understand limitations and advantages of MMIC, bolometric and heterodyne receivers and choose technology suitable for particular frequency band and application;
- understand basic principals of operation of superconducting detector and mixer components such as TES, HEB, SIS;
- understand basic principals of building cryogenic HEMT amplifiers and perform Y-factor measurements of amplifier noise temperature;
- understand principals of Gaussian beam technique and be able to simulate basic schemes of millimeter and Terahertz receiver coupling with antenna beam; understand basic principles, limitations and advantages of using Terahertz waveguides;
- understand principals of generation of MM-wave and Terahertz radiation;
- use knowledge on low-noise receiver technology for applications, e.g. radio astronomy, environmental science observations, or other applications;

Innehåll

The course largely relies on and uses the pre-required knowledge of microwave techniques, theory of transmission lines, and general understanding of physics. The course material covers the following topics:
- Noise and receiver properties at mm and submm frequencies, cryogenically operated receivers;
- Antenna - receiver coupling: Gaussian beam technique, Terahertz waveguides;
- Receiver types, e.g. direct detection (bolometric) and heterodyne, quasi-optical and waveguide-based; basics of operation for different type of receivers, schemes and applications;
- Bolometric receivers: theory, practical designs, examples;
- Heterodyne SIS receivers: theory, design, examples. Superconducting tuning circuitries;
- HEB heterodyne receivers: theory, design, examples.
- Terahertz MMICs: theory, design, examples.
- Generation of mm and submm waves: sources for local oscillators.
- HEMT cryogenic amplifiers: theory, design, examples.
- Superconductivity and thin-film processing for cryogenic and superconducting components: review of methods and technology.

Organisation

The course includes about 19 lectures, laboratory work (measuring the noise temperature of a cryogenic HEMT amplifier using Y-factor method), the course project made individually by every student (list of project topics will be offered to allow deeper studies on selected course material, e.g., design a quasi-optic coupling scheme with specified properties, propose and choose technology for environmental experiment with limb-sounder, etc.). All course events are compulsory and require student attendance.

Litteratur

The list of recommended literature to cover a wide course material, including journal papers and books will be provided via direct links to pdf files or links via Chalmers Library access. The Course RRY070 - MM-wave and Terahertz Technology (THzTech) details including the actual time schedule, literature, laboratory (tutorial) and Project could be found at the course web-page http://gard04.rss.chalmers.se/THzTech/THzTech_Course.htm

Examination

The assessment includes three steps: through the Course, students are tested by written mini-tests run at the beginning of every lecture (with result giving up to 10 point total), written course project (10 points); the laboratory work with report is compulsory for performing examination. A written examination completes the Course assessment (additional 40 points). The grade 3 is given for total collected points of 24-35, the grade 4 for total collected points of 36-47 and the grade 5 is given for more than 48 collected points.
