Use of the Theory of Characteristic Modes for Antenna Design and Analysis
The theory of characteristic Modes (TCM) was developed in the 1960’s, but started to be utilized and became useful only a decade ago (due to the advancements in computational electromagnetics). TCM is very helpful in predicting the potential radiation behavior of structures based on their geometries. If utilized properly, TCM can be used to design antenna systems that are very efficient and with controlled properties, (i.e. exciting certain modes purely can provide pattern reconfigurability). Unfortunately, there are several challenges associated with this design technique. TCM is always helpful in explaining the radiation phenomena and has been recently used to conduct what we call `antenna current engineering`. In this talk, I will touch upon the use of TCM in antenna design from theoretical and practical aspects. I will go over several challenges and show several applications from literature and the contribution of my group in this area as well.

Pr. Mohammad S. Sharawi of Polytechnique Montréal
Biography:
Mohammad S. Sharawi is a Professor of Electrical Engineering at Polytechnique Montréal, Montréal, Québec, Canada. He is also a member of the Poly-Grames Research Center at Polytechnique. He was with King Fahd University of Petroleum and Minerals (KFUPM), Saudi Arabia, between 2009 - 2018. He was the founder and director of the Antennas and Microwave Structure Design Laboratory (AMSDL) at KFUPM. He was a visiting Professor at the Intelligent Radio (iRadio) Laboratory, at the Electrical Engineering Department, University of Calgary, Alberta, Canada, during the Summer-Fall of 2014. He was a visiting research Professor at Oakland University during the summer of 2013.
Prof. Sharawi’s areas of research include Multiband Printed Multiple-Input-Multiple-Output (MIMO) Antenna systems, Reconfigurable and Active integrated Antennas, Applied Electromagnetics, Millimeter-wave MIMO antennas and Integrated 4G/5G antennas for wireless handsets and access points. He has more than 250 papers published in refereed journals and international conferences, 8 book chapters, one single authored book entitled “Printed MIMO Antenna Engineering,” Artech House, 2014, and the lead author of the recent book “Design and Applications of Active Integrated Antennas,” Artech house, 2018. He has 17 issued and 15 pending patents in the US Patent Office. He is serving as the Associate Editor for the IEEE Antennas and Wireless Propagation Letters (AWPL), IET Microwaves, Antennas and Propagation (MAP), as well as Wiley Microwave and Optical Technology Letters (MOP). He served on the Technical and organizational program committees of several international conferences such as EuCAP, APS, IMWS-5G, APCAP, iWAT among many others.
