Welcome to Lars Jonsson's home page at KTH
I am an Associate Professor since 2006 at
Electromagnetic Engineering (ETK) at Royal Institute of Technology (KTH)
which is located in the city of
Stockholm, Sweden. We are a group of people working in electromagnetic theory, antenna theory, scattering. Our interests includes electromagnetic material properties, nonlinear effects, communication channels, wide band antenna elements, phased arrays, breakdown processes, nanocomposites.
Currently I supervise a PhD student, Alireza Motevasselian, who is working on antennas and scattering from periodic surfaces. I and Associate Professor Hans Edin have superviced a visiting postdoctorial fellow Venkatesulu Bandapalle with an interest in electromagnetic breakdown processes. The group also have a two year postdoctorial fellow Andres Alayon Glazunov with interest in antenna/channel couplings. My fellow co-researcher is Associate Professor Martin Norgren and his PhD student Mariana Dalarsson. Anders Ellgardt is a researcher at the department with an interest in phased array antennas, communication and wide band antenna elements. Peter Fuks and Gunnar Larsson is also working with antennas, teaching and our lab. Saffan Ström is our professor emeritus. Professor Sailing He is another fellow co-research in electromagnetics with a group of students.
Research
For a list of published papers and more information see my
research page.
From 2012 we are participating in antenna research projects within the
CHASE network. Chase
is a VINN Excellence center around antenna systems. The project is about next generation array antennas, their design and properties.
A recent study was together with
Patrik Persson and a visitor Waqquas Bukkhsh, was a study on a communication antenna designed for satellite use.
Recently we have started to study how scattering limitations could be related
to antenna applications in the telecommunication sphere. We got our bridge proposal
"
Access technologies: multiple access, multiple users, multiple distributed antenna system" accepted. It is a joint
work with of different groups at KTH and LTH together with three Chinese universities. Here we have had some recent progress
on physical limits of array antennas.
Since 2010 we participates in a NFFP project on an AESA AEW Aperture solution.
This is a project together with SAAB Microwave System around antenna
elements possible for airborn antennas.
Teaching
During Autumn 2012 I will teach the part 1 of EI1110
and EI1102.
News/Info:
- The position is now filled. 2012-05-16
- The first interview requests has gone out. 2012-04-24.
- We have slowly started the evaluation which is tough since there are allot of good candidates that have applied. The application writing for the major fund organizations in Sweden is ongoing with deadline at the end of next week, which unfortunately slows the evaluation down until then. Completion of a few incomplete applications and a first contact with a few references has just started. The current expectation is that from the week starting with the 16:th of April we will begin to contact the top candidates with requests for interviews and visit invitations. 2012-04-03
- The adverticed PhD position that is now closed got 77 applicants, and we have started the evaluation. 2012-03-23.
