School of Electrical Engineering and Computer Science at KTH

Project description

Are you a driven and ambitious student with a passion for electromagnetic theory and mathematics? Do you want to be a part of a research group that aims for changing the way we think about electromagnetic design? If so, this Ph.D. project may be for you!

The research group, led by Professor Lars Jonsson, is dedicated to developing state-of-the-art designs, algorithms, and solutions for challenging design problems in array antennas, filters, and sensors. We use and develop mathematical theories, optimization tools, and computational realization to create innovative solutions that are often validated through measured prototypes. Our research is conducted in collaboration with industrial partners. Currently, we're focused on accelerating the extraction of properties of large systems by utilizing inherent 'sparse' properties as identified by model order reduction and energy passive (Herglotz-Nevanlinna) representations. We're exploring ways to improve the energy efficiency of GHz-frequency array antennas for communication and sensors with effective evaluation of electromagnetic properties of solutions to the exact covering problem. As well as determination and optimization of mutual coupling in large array systems to ensure interoperability between arrays. The research is expected to have both a strong theory component as well as a validation of the results, aiming to push fundamental boundaries of what is possible in electromagnetic design.

The Ph.D. project has several possible research directions aiming towards a better understanding of the effective electromagnetic design as governed by Maxwell´s equations. The direction within the project will be determined in collaboration with the Ph.D. candidate. Join us and be a part of a paradigm shift in electromagnetic design that is changing the way we think and do things.

Third-cycle subject: Electrical Engineering 

Supervision: Prof. Lars Jonsson with co-supervision of Yevhen Ivanenko. 

What we offer

Admission requirements

To be admitted to postgraduate education (Chapter 7, 39 § Swedish Higher Education Ordinance), the applicant must have basic eligibility in accordance with either of the following:

  • passed a second cycle degree (for example a master's degree), or
  • completed course requirements of at least 240 higher education credits, of which at least 60 second-cycle higher education credits, or
  • acquired, in some other way within or outside the country, substantially equivalent knowledge

The successful candidate will hold a Master of Science (or equivalent, e.g. Civilingenjör in Sweden) in Electrical Engineering, Engineering Physics, or Engineering Mathematics. 

In addition to the above, there is also a mandatory requirement for English equivalent to English B/6, read more here


In order to succeed as a doctoral student at KTH you need to be goal oriented and persevering in your work. During the selection process, candidates will be assessed upon their ability to:

  • independently pursue his or her work
  • collaborate with others,
  • have a professional approach and
  • analyse and work with complex issues.

We're looking for someone with a strong background in electromagnetic theory, mathematics, optimization and/or scientific computation.

After the qualification requirements, great emphasis will be placed on personal competency. 

Target degree: Doctoral degree

Information regarding admission and employment

Only those admitted to postgraduate education may be employed as a doctoral student. The total length of employment may not be longer than what corresponds to full-time doctoral education in four years' time. An employed doctoral student can, to a limited extent (maximum 20%), perform certain tasks within their role, e.g. training and administration. A new position as a doctoral student is for a maximum of one year, and then the employment may be renewed for a maximum of two years at a time. In the case of studies that are to be completed with a licentiate degree, the total period of employment may not be longer than what corresponds to full-time doctoral education for two years.
