His main field of research is electromagnetics and microwaves, and he is especially experienced in applied computational electromagnetics. He heavily participated in the development of time-domain and frequency-domain numerical analysis tools for new applications and contributed to research on improving the accuracy and speed of the algorithms being developed. He is experienced in designing RF/microwave circuits and antennas for the related technologies, and performing experimental characterizations of these devices. Dr Demir is a member of IEEE, ACES, and SigmaXi, has co-authored more than 50 technical journal and conference papers, and served as a technical program co-chair for the 2014 IEEE International Symposium on Antennas and Propagation and USNC-URSI Radio Science Meeting and for the ACES 2015 conference.
