This publication provides a comprehensive and systematically organized coverage of higher order finite-difference time-domain or FDTD schemes, demonstrating their potential role as a powerful modeling tool in computational electromagnetics. Special emphasis is drawn on the analysis of contemporary waveguide and antenna structures. Acknowledged as a significant breakthrough in the evolution of the original Yee's algorithm, the higher order FDTD operators remain the subject of an ongoing scientific research.

Produktbeschreibung
This publication provides a comprehensive and systematically organized coverage of higher order finite-difference time-domain or FDTD schemes, demonstrating their potential role as a powerful modeling tool in computational electromagnetics. Special emphasis is drawn on the analysis of contemporary waveguide and antenna structures. Acknowledged as a significant breakthrough in the evolution of the original Yee's algorithm, the higher order FDTD operators remain the subject of an ongoing scientific research. Among their indisputable merits, one can distinguish the enhanced levels of accuracy even for coarse grid resolutions, the fast convergence rates, and the adjustable stability. In fact, as the fabrication standards of modern systems get stricter, it is apparent that such properties become very appealing for the accomplishment of elaborate and credible designs.
Autorenporträt
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. Theodoros D. Tsiboukis received the Diploma Degree in electrical and mechanical engineering from the National Technical University of Athens, Athens, Greece, in 1971, and the Doctor Engineer Degree from the Aristotle University of Thessaloniki (AUTH), Thessaloniki, Greece, in 1981. From 1981 to 1982, he was with the Electrical Engineering Department, University of Southampton, U.K., as a Senior Research Fellow. Since 1982, he has been with the Department of Electrical and Computer Engineering (DECE), AUTH, where he is currently a Professor. He has served in many administrative positions, including Director of the Division of Telecommunications at the DECE (1993-1997) and Chairman of the DECE (1997-2001). He is also the Head of the Advanced and Computational Electromagnetics Laboratory at the DECE. His main research interests include electromagnetic field analysis by energy methods, computational electromagnetics (FEM, BEM, vector finite elements, MoM, FDTD method, absorbing boundary conditions), inverse problems, EMC applications and metamaterials. He has authored or coauthored six books, over 120 refereed journal papers and over 100 international conference papers. He was the Guest Editor of a Special Issue of the International Journal of Theoretical Electrotechnics (1996). Dr. Tsiboukis is a member of various societies, associations, chambers and institutions. He was the chairman of the local organizing committee of the 8th International Symposium on Theoretical Electrical Engineering (1995). He has been the recipient of several awards and distinctions.
