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 (FIT, CST microwave studio solver). 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).

“…In this framework, a constant demand exists for reliable and efficient numerical tools to characterize such media over large frequency bandwidth (from direct current to tens of GHz), including but not restricted to applications such as electromagnetic interference/compatibility (EMI/EMC), 5G networks, more electrical aircrafts/automobiles. The state-of-the-art regarding fullwave electromagnetic (EM) modeling shows that various methods were successfully used to simulate composite fiber-reinforced media including models in frequency domain (finite element method [1], integral equation [2]), and time domain (finite difference [3], discontinuous Galerkin [4], finite integral technique (FIT) [5]). However, due to the intrinsic variability of composite materials (e.g., conductivity, locations or shapes of inclusions, .…”

This article proposes an advanced methodology to deal with the complexity of composite materials modeling up to 60 GHz. For radiofrequency (RF) requirements, it has been demonstrated that the distribution of conductive inclusions plays a major role. Since their locations are intrinsically subject to uncertain assumptions, the Monte Carlo (MC) technique is considered as a golden standard. Unfortunately, the computational costs involved by coupling full-wave electromagnetic (EM) simulations and MC remains prohibitive. The aim of this proposal is to demonstrate the interest of stochastic reduced order method (SROM) to tackle computational constraints, jointly with the statistical precision needed for a realistic description of RF composites.
