Job description

We are seeking a postdoctoral researcher to conduct research on advanced lens antennas for millimeter-wave and sub-THz systems. The research focuses on artificial electromagnetic materials and periodic structures for wave manipulation, with applications in high-performance antenna systems.

The project includes analysis, design, and experimental validation of lens antennas based on physical optics, transformation optics, metasurfaces, and glide-symmetric structures. The work involves the development of electromagnetic models, numerical simulations, prototype realization, and measurements, as well as dissemination of research results through leading international journals and conferences.

The successful candidate will work closely with international collaborators and contribute to the supervision of MSc students and doctoral researchers.

Qualifications

Requirements

• A doctoral degree or an equivalent foreign degree, in Electrical Engineering, Engineering Physics, or a related field. This eligibility requirement must be met no later than the time the employment decision is made.
• Demonstrated research expertise in electromagnetics and antenna engineering.
• Strong background in physical optics and high-frequency electromagnetics. 
• Experience in the analysis and design of antennas or electromagnetic components. 
• Experience with numerical electromagnetic methods and commercial simulation tools such as CST Microwave Studio or Ansys HFSS.
• Proven ability to publish research results in international journals and conferences.
• Excellent written and oral communication skills in English as this is needed in the daily work.

Preferred qualifications

• A doctoral degree or an equivalent foreign degree, obtained within the last three years prior to the application deadline
• Demonstrated research experience in lens antennas.
• Experience with metasurfaces or other periodic electromagnetic structures.
• Experience with glide-symmetric structures and dispersion analysis of periodic media. 
• Experience with millimeter-wave or sub-THz systems.
• Experience in antenna measurements and experimental validation.
• Teaching experience and supervision of students.
• Experience in international research collaborations.
• For KTH and the research group, awareness of diversity, gender equality, and equal treatment issues are important.   

Great emphasis will be placed on personal skills.
