Abstract

The aim of this proposal is to demonstrate the ability of tridimensional (3-D) electromagnetic modeling tool for the characterization of composite materials in microwave frequency band range. Indeed, an automated procedure is proposed to generate random materials, proceed to 3-D simulations, and compute shielding effectiveness (SE) statistics with finite integration technique. In this context, 3-D electromagnetic models rely on random locations of conductive inclusions; results are compared with classical electromagnetic mixing theory (EMT) approaches (e.g. Maxwell-Garnett formalism), and dynamic homogenization model (DHM). The article aims to demonstrate the interest of the proposed approach in various domains such as propagation and electromagnetic compatibility (EMC).

Lallechere

Sébastien Lalléchère was born in Nevers (France) in 1979. He obtained his Master and PhD degrees respectively in computational modeling and electronics/electromagnetism from Polytech’Clermont (2002) and Université Blaise Pascal (UBP, 2006), both in Clermont-Ferrand, France. He served as research engineer in Institut Pascal (2007) granted by ANR program CISSSI focusing on intensive computational methods for electromagnetics. He joined Institut Pascal (IP) and Université Blaise Pascal (UBP), Clermont-Ferrand (France) as an Associate Professor in September 2007. His research interests cover the fields of electromagnetic compatibility (EMC) including antennas and propagation, complex and reverberating electromagnetic environments, computational electromagnetics, numerical stochastic modeling, reliability and sensitivity analysis in electrical engineering. He received funding grants for visiting appointments in 2006 and 2014 from French Foreign Affairs/Research Ministries and UBP for scientific stays respectively in ETH Zurich (Switzerland) and University of Split (Croatia). Dr. Lalléchère is an URSI corresponding member (Commission E "EM environment and interferences"), member of IEEE (EMC, MTT, AP societies), Applied Computational Electromagnetics Society (ACES) and of the French Electrical Engineering Society (SEE).
