Nikolaos V. Kantartzis received the Diploma degree and Ph.D. degree in electrical and computer engineering from the Aristotle University of Thessaloniki (AUTH), Thessaloniki, Greece, in 1994 and 1999, respectively. In 1999, he joined the Applied and Computational Electromagnetic Laboratory, Department of Electrical and Computer Engineering, AUTH, as a Postdoctoral Research Fellow. He has authored or coauthored several refereed journal papers in the area of computational electromagnetics and especially higher order finite-difference time-domain (FDTD) method, perfectly matched layers (PMLs), nonorthogonal discretization algorithms, vector finite elements and alternating-direction implicit (ADI) formulations. His main research interests include time- and frequency-domain electromagnetic and acoustic analysis, EMC modeling, modern microwave circuits, antenna structures and metamaterials.
