Infos

Metamaterials-artificially structured materials with engineered electromagnetic properties-have enabled unprecedented flexibility in manipulating electromagnetic waves and producing new functionalities. This book details recent advances in the study of optical metamaterials, ranging from fundamental aspects to up-to-date implementations, in one unified treatment. Important recent developments and applications such as superlens and cloaking devices are also treated in detail and made understandable. The planned monograph can serve as a very timely book for both newcomers and advanced researchers in this extremely rapid evolving field.

Vladimir M. Shalaev received his PhD with honors from Krasnoyarsk University, Russia, in 1983.  He has since worked in the following fields: nanophotonics, metamaterials and plasmonics.  His honors inlude:  The College of Engineering Research Excellence Award, Nanotech Briefs Nano 50(TM) Award in the Technology category, 2006; Robert and Anne Burnett Professor of Electrical and Computer Engineering, Purdue University, since 2004; Fellow of The International Society for Optical Engineering (SPIE); Fellow of the American Physical Society, since 2002; Fellow of the Optical Society of America, since 2003.

Wenshan Cai received his B.S. and M.S. degrees in Electronic Engineering from Tsinghua University in 2000 and 2002, respectively. From 2002 to 2008, he worked for his PhD degree in Electrical and Computer Engineering at Purdue University. He is now with the Geballe Laboratory for Advanced Materials at Stanford University. His research areas of interest include optical metamaterials, plasmonics optics, optoelectronics, and nanoscale photonic materials and devices. His honors include: Optical Society of America New Focus/Bookham Student Award, 2008, Chinese Government Award for Outstanding Students Abroad, 2007, Nanotech Briefs Nano 50 Award, 2006, Graduate with honor, Tsinghua University, 2002, Yangtze Fellowship for academic distinction, Tsinghua University, 2002, Motorola Fellowship for academic distinction, Tsinghua University, 2001.
