DESCRIPTION:Prof. Piero Triverio\, University of Toronto\nElectromagnetic 
 simulations play a crucial role in the design of antennas\, integrated cir
 cuits\, and power grids. Unfortunately\, the multiscale structure of many 
 practical designs defies even the best method of moments (MoM) solvers. Fo
 r example\, while metasurface antennas have thousands of unit cells\, exis
 ting simulators can barely handle a few cells.\n\nWe present a new macromo
 deling concept to efficiently model multiscale objects in MoM solvers. Giv
 en a closed surface S\, the proposed macromodels are able to capture the e
 lectromagnetic response of the enclosed objects using only an equivalent e
 lectric current distribution on S. This current is related to the tangenti
 al electric field using a novel surface admittance operator. We show that 
 a single macromodel can accurately capture the electromagnetic response of
  an intricate metasurface unit cell\, leading to significant savings over 
 a state-of-art MoM solver in terms of CPU time (up to 24X) and memory cons
 umption (up to 12X).\n\nWe also show that the proposed operators can accur
 ately model skin effect in conductors of arbitrary shape. This approach is
  computationally efficient\, since it requires only a surface mesh\, but b
 roadband and Maxwell-accurate. We present examples related to the electrom
 agnetic analysis of 3D integrated circuits and underground cables for ener
 gy distribution.\n\nBio: Piero Triverio received the Ph.D. degree in Elect
 ronic Engineering from Politecnico di Torino\, Italy\, in 2009. He is an A
 ssociate Professor in the Department of Electrical & Computer Engineering 
 at the University of Toronto\, and in the Institute of Biomaterials and Bi
 omedical Engineering. He holds the Canada Research Chair in Computational 
 Electromagnetics. His research interests include signal integrity\, comput
 ational electromagnetism\, model order reduction\, and computational fluid
  dynamics applied to cardiovascular diseases.\n\nProf. Triverio received t
 he Best Paper Award of the IEEE Transactions on Advanced Packaging (2007)\
 , the EuMIC Young Engineer Prize (2010)\, the Connaught New Researcher Awa
 rd (2013)\, and the Ontario Early Researcher Award (2016). Triverio and hi
 s students won several awards at international conferences\, including the
  Best Paper Award of the IEEE Conference on Electrical Performance of Elec
 tronic Packaging and Systems (2008\, 2017).
