Richard W. Ziolkowski博士现为美国亚利桑那大学电子与计算机工程系冠名教授、光学学院教授。由于在IEEE与OSA领域作出的杰出贡献，他不仅同时为IEEE协会与OSA协会的会士，而且于2005年受聘为IEEE天线与电波传播协会主席。
Richard W. Ziolkowski
is the Litton Industries John M. Leonis Distinguished Professor in the
Department of Electrical and Computer Engineering and is a Professor in the
College of Optical Sciences at the University of Arizona. He is a Fellow of both IEEE and OSA. He was
President of the IEEE Antennas and Propagation Society in 2005. He was awarded an honorary doctoral degree
(Doctor Technish Honoris Causa) from the Technical University of Denmark in
2012. He was the 2014-2015 Australian DSTO Fulbright Distinguished Chair in
Advanced Science and Technology and was attached to the Aerospace Composite
Technologies team of the Defence Science and Technology Organization at
Fisherman’s Bend, Melbourne, Australia. He was the Computational Electronics
and Electromagnetics Thrust Area Leader in the Engineering Research Division at
the Lawrence Livermore National Laboratory before joining the University of
Arizona in 1990.
The introduction of metamaterials and
metamaterial-inspired structures into the tool set of RF engineers has led to a
wide variety of advances in discovery within the antennas and propagation
research areas. The enhanced awareness of complex media, both naturally
occurring and artificially constructed, which has been stimulated by the debut
of metamaterials, has enabled paradigm shifts in terms of our understanding of
how devices and systems operate and our expectations of their performance
characteristics. These shifts include the trends of miniaturization, enhanced
performance, and multi-functionality of antenna systems for wireless platforms;
dispersion engineering to modify the properties, for example, of transmission
lines and antennas; scattering mitigation (cloaking, active jamming, perfect
absorbers) and enhancements (sensors, detectors); and the tailoring output
beams (leaky wave broadside radiators, sub-diffraction limit resolution in
remote sensing and highly directive beams for energy transfer and low
probability of intercept systems).
