Event Description
Metasurfaces are artificial surfaces which are engineered to interact with electromagnetic waves to achieve wide variety of functionalities. They can act as smart reflectors where one can envision them being used on walls and windows and make our buildings smarter, or they can be used as electromagnetic shields which can intelligently prevent us from electromagnetic exposure and even give false appearances and make illusions. This lecture will focus on the fundamentals of such electromagnetic metasurfaces and discuss exciting application scenarios where these engineered surfaces may be employed and impact our daily lives.

About the speaker :
Shulabh Gupta received the Bachelors in Technology (B.Tech.) degree in electronic engineering from the Indian Institute of Technology (Indian School of Mines), Dhanbad, India, in 2004, the Masters of Science (M.S.) degree in telecommunications from Institut National de la Recherche Scientifique Energie Materiaux Telecommunications Research Center (INRS-EMT), Universite du Quebec, Montreal, QC, Canada, in 2006, and the Ph.D. degree in electrical engineering from the Ecole Polytechnique of Montreal, Montreal, QC, Canada, in 2012. From December 2009 to May 2010, and then in Summer 2018, he was a Visiting Research Fellow with the Tokyo Institute of Technology, Tokyo, Japan, where he was involved in the design of high gain mm-Wave antennas and metasurface. He worked as a Postdoctoral Fellow at the University of Colorado at Boulder after finishing his PhD, in 2012, where he was working on the design and characterization of high-power UWB antennas. He later joined the University of Hong Kong between 2012-2014 as a post-doctoral fellow where his research concerned with multi-functional traveling-wave leaky-wave antennas for RFID and imaging applications. He was later the postdoctoral fellow in the electrical engineering department of Ecole Polytechnique of Montreal, Montreal, QC, Canada from April 2014 to Jan 2016. Since March 2016, He joined as an assistant professor in the department of electronics (DoE) at the Carleton University, in Ottawa. His general research interest is in high gain antennas, electromagnetic metamaterials and their applied physics applications ranging from mm-wave to optics.
