“…Several factors control the electromagnetic response of CNT composites, such as the spatial distribution of CNTs [8]- [10], CNT volume fraction [11], average length of embedded CNTs [12], [13], interaction among CNTs [13], [14], conductivity of CNTs (single wall/multi wall) [11], [15], waviness of CNTs (nearly straight to highly crumpled) [16], [17], CNT interaction with matrix, matrix properties, and dimensions [18], [19]. Thus, finding an efficient method capable of accurately quantifying the interactions among CNTs, interactions of CNTs with the embedding layers, and with the incident electromagnetic excitation is critical for understanding and optimizing the electromagnet response of CNT reinforced composites.…”

Modeling the electromagnetic response of carbon nanotube (CNT) reinforced composites is inherently a threedimensional (3D) multi-scale problem that is challenging to solve in real-time for nondestructive evaluation applications. This article presents a fast and accurate full-wave electromagnetic solver based on a multi-layer dyadic Green's function approach. In this approach, we account for the effects of the dielectric slab, where the CNTs are embedded, without explicitly discretizing its interfaces. Due to their large aspect ratios, the CNTs are modeled as arbitrary thin wires (ATWs), and the method of moment (MoM) formulation with distributed line impedance is used to solve for their coupled currents. The accuracy of the inhouse solver is validated against commercial method of moment (MoM) and finite element method (FEM) solvers over a broad range of frequencies (from 1 GHz to 10 THz) and for a wide range of dielectric slab properties. Examples of 100 nm long vertical and horizontal CNTs embedded in a 1 µm thick lossy dielectric substrate are presented. The in-house solver provides more than 50 × speed up while solving the vertical CNT, and more than 570 × speed up while solving the horizontal CNT than a commercial MoM solver over the GHz to THz frequency range.Index Terms-Arbitrary thin wire (ATW), carbon nanotubes (CNTs), electric field integral equation (EFIE), method of moment (MoM), multilayer dyadic Green's function, Sommerfeld integrals (SI).

The production of sports equipment necessitates a delicate balance between comfort, performance, and safety. Achieving this equilibrium depends on a profound understanding of material chemistry and the biomechanical considerations that come into play as athletes push their bodies to the limits. In recent years, composite materials have gained substantial attention for their impressive mechanical and physical properties. Among these, carbon nanotube (CNT) reinforced magnesium matrix composites (MMCs) have emerged as promising contenders. These materials are synthesized using powder metallurgy and hot extrusion techniques, capitalizing on CNTs’ unique properties to enhance the mechanical characteristics of magnesium-based materials. This study delves into the parametric optimization of CNT-reinforced MMCs, particularly focusing on microstructure design. Leveraging a homogenization-based optimization system, we investigate both material properties and shape optimization. Finite element numerical simulations validate our predictions, showcasing significant improvements in various parameters, most notably alterations in fiber layup angles, which contribute to enhanced performance characteristics. This approach serves as an invaluable tool for streamlining composite structure design while simultaneously reducing the costs associated with traditional experimental methods. By harnessing the potential of CNT-reinforced MMCs and optimization techniques, this research advances sports equipment design, ultimately ensuring athletes’ safety and the optimization of their performance.
