Frequency Selective Surfaces (FSS) are well known in the literature 
for their filtering characteristics at microwave and millimeter wave 
frequencies.  Traditional FSS filters are comprised of a doubly 
periodic metallic screen printed on a dielectric substrate and are 
sometimes referred to in the infrared (IR) as metallodielectric 
photonic crystals (MDPCs). Metallodielectric FSS have also been 
synthesized at microwave frequencies to exhibit metamaterial 
properties such as artificial magnetic conducting, negative 
refractive index and zero refractive index behavior. This research 
naturally extends to synthesizing negative index metamaterials (NIM) 
and zero index metamaterials (ZIM) in the IR and optical bands. For 
applications at visible wavelengths, metallic losses can degrade the 
performance of metallodielectric FSS, whereas low loss dielectric 
materials are readily available. Thus, all-dielectric FSS (DFSS) are 
also being investigated for filtering applications in the near-IR and 
optical regimes. This talk will provide an overview of research in 
the area of FSS-based metamaterials, with an emphasis on work being 
done at the Pennsylvania State University Computational 
Electromagnetics and Antennas Research Lab (PSU CEARL). Other types 
of novel metamaterials under development by the PSU CEARL group will 
also be discussed. An emphasis will be placed on the computational 
modeling tools developed specifically for the analysis and design 
optimization of electromagnetic metamaterial performance.

Dr. Douglas H. Werner received the B.S., M.S., and Ph.D. degrees in 
electrical engineering and the M.A. degree in mathematics from The 
Pennsylvania State University (Penn State), University Park, in 1983, 
1985, 1989, and 1986, respectively.

He is a Professor in the Pennsylvania State University, Department of 
Electrical Engineering. He is also the director of the Computational 
Electromagnetics and Antennas Research Lab (CEARL) 
http://labs.ee.psu.edu/labs/dwernergroup/ as well as a member of the 
Communications and Space Sciences Lab (CSSL). He is also a Senior 
Scientist in the Computational Electromagnetics Department of the 
Applied Research Laboratory and a faculty member of the Materials 
Research Institute (MRI) at Penn State. Dr. Werner was presented with 
the 1993 Applied Computational Electromagnetics Society (ACES) Best 
Paper Award and was also the recipient of a 1993 International Union 
of Radio Science (URSI) Young Scientist Award. In 1994, Dr. Werner 
received the Pennsylvania State University Applied Research 
Laboratory Outstanding Publication Award. He was a co-author (with 
one of his graduate students) of a paper published in the IEEE 
Transactions on Antennas and Propagation which received the 2006 R. 
W. P. King Award. He has also received several Letters of 
Commendation from the Pennsylvania State University Department of 
Electrical Engineering for outstanding teaching and research. Dr. 
Werner is a former Associate Editor of Radio Science, an Editor of 
the IEEE Antennas and Propagation Magazine, a Fellow of the IEE and 
the IEEE, a member of the American Geophysical Union (AGU), URSI 
Commissions B and G, the Applied Computational Electromagnetics 
Society (ACES), Eta Kappa Nu, Tau Beta Pi and Sigma Xi. He has 
published numerous technical papers and proceedings articles and is 
the author of eight book chapters. He edited a book entitled 
Frontiers in Electromagnetics (Piscataway, NJ: IEEE Press, 2000). He 
has also contributed a chapter for a book entitled Electromagnetic 
Optimization by Genetic Algorithms (New York: Wiley Interscience, 
1999) as well as for the book entitled Soft Computing in 
Communications (New York: Springer, 2004). He has recently completed 
work on a new book (co-authored with Randy Haupt) entitled Genetic 
Algorithms in Electromagnetics to be published by Wiley. He has also 
recently completed an invited chapter on "Fractal Antennas" for the 
new edition of the popular Antenna Handbook published by McGraw-Hill. 
He was the recipient of a College of Engineering PSES Outstanding 
Research Award and Outstanding Teaching Award in March 2000 and March 
2002 respectively. He was also recently presented with an IEEE 
Central Pennsylvania Section Millennium Medal.

His research interests include theoretical and computational 
electromagnetics with applications to antenna theory and design, 
phased arrays, microwave devices, wireless and personal communication 
systems, wearable and e-textile antennas, frequency selective 
surfaces, electromagnetic wave interactions with complex media, 
metamaterials, electromagnetic bandgap materials, zero and negative 
index materials, fractal and knot electrodynamics, tiling theory, 
neural networks, genetic algorithms and particle swarm optimization.
