DESCRIPTION:Christophe Caloz\, École Polytechnique of Montréal\nBio: Chr
 istophe Caloz received the Diplôme d'Ingénieur en Électricité and the 
 Ph.D. degree from École Polytechnique Fédérale de Lausanne (EPFL)\, Swi
 tzerland\, in 1995 and 2000\, respectively. From 2001 to 2004\, he was a P
 ostdoctoral Research Fellow at the Microwave Electronics Laboratory\, Univ
 ersity of California at Los Angeles (UCLA). In June 2004\, Dr. Caloz joine
 d École Polytechnique of Montréal\, where he is now a Full Professor\, t
 he holder of a Canada Research Chair (CRC) and the head of the Electromagn
 etics Research Group. He has authored and co-authored over 550 technical c
 onference\, letter and journal papers\, 13 books and book chapters\, and h
 e holds several patents. His works have generated about 13\,000 citations\
 , and he is a Thomson Reuters Highly Cited Researcher. Dr. Caloz is a Memb
 er of the Microwave Theory and Techniques Society (MTT-S) Technical Commit
 tees MTT-15 (Microwave Field Theory) and MTT-25 (RF Nanotechnology)\, a Sp
 eaker of the MTT-15 Speaker Bureau\, the Chair of the Commission D (Electr
 onics and Photonics) of the Canadian Union de Radio Science Internationale
  (URSI) and an MTT-S representative at the IEEE Nanotechnology Council (NT
 C). In 2009\, he co-founded the company ScisWave\, which develops CRLH sma
 rt antenna solutions for WiFi. Dr. Caloz received several awards\, includi
 ng the UCLA Chancellor’s Award for Post-doctoral Research in 2004\, the 
 MTT-S Outstanding Young Engineer Award in 2007\, the E.W.R. Steacie Memori
 al Fellowship in 2013\, the Prix Urgel-Archambault in 2013\, and many best
  paper awards with his students at international conferences. He has been 
 an IEEE Fellow since 2010 and an IEEE Distinguished Lecturer for the Anten
 nas and Propagation Society (AP-S) since 2014. In 2014\, he was elected as
  a member of the Administrative Committee of AP-S. He is currently also a 
 Distinguished Adjunct Professor at King Abdulaziz University (KAU)\, Saudi
  Arabia. His research interests include all fields of theoretical\, comput
 ational and technological electromagnetics\, with strong emphasis on emerg
 ent and multidisciplinary topics\, including particularly metamaterials\, 
 nanoelectromagnetics\, exotic antenna systems and real-time radio.\nEveryt
 hing in our universe occurs in space\, time\, and spacetime where space an
 d time are interdependent. These concepts are therefore fundamental across
  all areas of human activities\, including history\, economy\, philosophy\
 , arts and sciences.\nThe author believes systematic endeavours in manipul
 ating waves in space\, time and spacetime will bring about considerable op
 portunities towards the development of tomorrow’s electromagnetic scienc
 e and technology.\nManipulation waves in space essentially consists in eng
 ineering their spatial frequency (k) spectrum\, which may be performed usi
 ng conventional electromagnetic structures\, such as apertures\, antennas\
 , lenses\, polarizers\, photonic crystals\, Talbot imagers\, optical masks
 \, etc. However\, the frontiers of spatial dispersion engineering may be p
 ushed far beyond the current state of the art\, particularly using the nov
 el concept of metasurfaces. The talk will present several innovations in t
 his area\, including magnetless nonreciprocal gyrotropy\, generalized refr
 action\, multiple wave transformation\, multi-refringence\, and orbital an
 gular momentum multiplexing.\nIn time\, manipulating waves essentially con
 sists in engineering their temporal frequency (w) spectrum\, as partly don
 e in ultrafast optics where oscillations are too fast to be handled by dig
 ital signal processors\, and where real-time chirping and nonlinear materi
 als and devices have therefore to be used instead. Such concepts have been
  little explored in electromagnetics\, and may represent a solution to the
  exploding demand for faster and more reliable radio if sufficient progres
 s is made. The author developed in his group metamaterial-inspired structu
 res called phasers\, which provide specifiable group delay versus frequenc
 y responses to perform unprecedented temporal dispersion engineering. The 
 talk will present the related Radio Analog Signal Processing (R-ASP) conce
 pt and technology\, and demonstrate a number of related applications\, suc
 h as spectrum sniffing\, real-time Fourier analysis\, and dispersion code 
 multiple access.\nAforementioned concepts typically concern monochromatic 
 spatial dispersion engineering and mono-directional temporal dispersion en
 gineering. Combining the two aspects in simultaneous space and time disper
 sion engineering\, as nature does it in rainbows and humans in holograms\,
  will open up further horizons in electromagnetics processing. The talk wi
 ll also address this area\, first introducing the fundamental concept of t
 emporal to spatial frequency mapping\, and next describing a few recent ap
 plications\, including real-time spectrogram analysis and two-dimensional 
 mapping for the processing of ultrafast waves.\nFinally\, novel concepts i
 n electromagnetic spacetime discontinuities\, where space and time are int
 erdependent as in the theories of special and general relativity\, will be
  introduced and discussed as a potential platform for future developments 
 in electrodynamics.
