New information regarding the course is given below:
14/12 Course evaluation 2209, scale 1-5: Goals 4.5, literature 4.4, lectures 4.8, assignments 4.3, projects 4.7,laboratory session 4.5, overall impression 4.6
7/12 Assignment 2 has been graded. Please pick up your solutions. If there is a return or correct on it you need to correct it and give it back to Anders. There are still some students who haven't picked up the graded assignment 1.
2/12 You may now sign up for the project presentations. Unfortunately it is not possible to indicate the project on the list. You may send me an email and tell me when you have signed up and what project you have. In that way I can make sure that we don't have too many presentations of one project at the same occasion. Notice that it is important that only one per group sign up.
2/12 For assignment number 3: In problem 2 you may either solve the problem by consider the resonator to be a waveguide of finite length. You may also solve it in 3D. To obtain an elliptic cylinder you first draw a circular cylinder and then you scale it in the x (or y) direction. This is done by using draw-modify-scale.
27/11 We will have the presentations of the projects on Thursday 8-10, Thursday 15-17 and Friday 8-10. I will have a list on this page where you can sign up.
27/11 Here are the presentations I gave Monday 23/11, Thursday 26/11 and Friday 27/11.
24/11 Some have had problems with the Comsol problems in assignment 2. This is due to that eigenfrequency or eigenvalue have been chosen when calculating the cut-off frequencies. One should choose mode analysis and effective mode index as in example 6.4. The information in the book and in the problem text is not the best. The eigenfrequency is, in the new versions of Comsol, not the same as the cut-off frequency.
23/11 The last assignment will be handed out today. You may download it from home exercises.
18/11 I hope to have graded the first assignment on Monday. In the second assignment it is a little bit tricky to obtain the bandwidth that is required for the ridge waveguide. The trick is to make the ridge wide, much wider than what is used in the book.
16/11 Since there is a laboratory session on Thursday 8-12 the problem session Thursday 8-10 is cancelled.
16/11 If you haven't signed up for the laboratory session please contact Anders as soon as possible. The laboratory sessions are on Tuesday 17/11 8-12 and 13-17, Wednesday 8-12 and Thursday 8-12. Notice that the first list with only three sessions is not valid.
15/11: On Monday 16/11, 15-17, Göran Jönsson will give a lecture as a preparation for the laboratory session. I recommend everyone to attend Görans lecture. You find his lecture notes here:
BW-version(printout version) Color-version (screen version)
12/11 On Monday December 7 we will have a study visit at Maxlab at 8.15-10. We meet at the main entrance to Maxlab at 8.10.
12/11 Here are the instructions for the laboratory session: Instructions
9/11 The list of projects are available on Thursday. You are aloud to work in group of two students. You sign up for one of the problems on the list. You may wait a couple of days before you decide on what project you pick.
9/11 Assignment 2 will be handed out today. You also find it under home exercises in the menu to the left.
This course is given for the E, F, Pi programs, and the master program in Photonics. The course focuses on the basic theories for waveguiding structures and on the analysis of optical and microwave devices with the finite element method (FEM). The software package COMSOL, which is available for the students at LTH, is used throughout the course to analyze complicated structures. Since Maxlab IV and ESS are to be built in Lund a part of the course aims at explaining the basic principles for particle accelerators. There is also a study visit at Maxlab where we are guided through the facility and are informed about the new Maxlab IV.
The examination of the course is by hand-in problems during the course and by a minor project at the end of the course. There is one laboratory session and this is devoted for the network analyzer. The network analyzer is an important instrument for measurements at high frequencies and is invaluable for microwave engineers and experimental physicists.
The literature is the book Microwave theory by Anders Karlsson and Gerhard Kristensson. This book has been translated from Swedish to English this year. A number of new sections has been added to the book and also a number of examples based on COMSOL. The book can be bought at the kursexpedition, which is located on the third floor in the E-building (the stairs to the north in the high building).
Kursexpeditionen is open Monday-Thursday 09.45-11.30 and 12.45-13.15.
This page will contain all information and material that is handed out during the course. Please contact Anders Karlsson (anders.karlssonATeit.lth.se) if you have questions.
