Josip Lončar

Josip Lončar is an Assistant Professor at the Department of Radio Communications, Faculty of Electrical Engineering and Computing, University of Zagreb. His research focuses on high-frequency electronics, stability analysis of networks with non-Foster elements, and active/passive metasurfaces. He holds a PhD from the University of Zagreb (2017) and has collaborated with institutions such as the Radiation Laboratory at the University of Michigan and Fuzhou University. He teaches courses including 'Innovative Electromagnetic Systems' and 'Microwave Electronics'. Lončar has received awards including the Rektorova nagrada for biomedical engineering work and an Osijek City Scholarship (2009–2013).

His research projects include 'Optical Communication Systems with Extended Resonant Gaps' (HRZZ-funded), 'Non-Foster Source-Load Networks' (EOARD-funded), and 'Metamaterial Structures for Electromagnetic Energy Guidance' (UKF-funded). He has contributed to advancements in CubeSat antenna design, attitude control systems, and active metasurface applications. Lončar’s work bridges theoretical electromagnetic analysis with practical implementations in aerospace and biomedical engineering.
