This article presents an optimal connection topology to model the voltage-exchange at the interface between different sub-grids in nonstructured TLM meshes. As a first step, the derivation—using Kirchhoff's circuit laws—of these voltage-exchange equations between two subdomains with an arbitrary meshing ratio and a specific connection topology...

This article revisits the ideal transformer model used at the interface between different sub-grids in non-structured TLM meshes. The derivation of the voltage-exchanges equations between two subdomains with an arbitrary meshing ratio and connection topology is presented. The voltage-exchanges process is then generalized as a scattering-matrix...

In lossy dielectrics (e.g., human tissues) the skin effect plays a major role in Electromagnetic (EM) waves propagation as frequencies increase. This skin effect indicates that EM-waves decay exponentially as they penetrate good conductors, and they practically vanish as they traverse a distance of few skin depths. Moreover, in such media, the...

Numerical dosimetry is an essential procedure in designing and optimizing propagating EM-devices that confirm to the recommended limits of Specific Absorption Rate (SAR). However, as frequencies go higher, the complexity of the computational problem increases substantially. Moreover, the high heterogeneity of the human body and the uncertainty...

Cet article consiste à effectuer des études dosimétriques dans des milieux hétérogènes dans les bandes de fréquence de la 5G et au -delà pour fournir des estimations de niveaux de DAS. A ces fréquences, la distribution de DAS devient surfacique, aussi afin d'étudier l'influence de la répartition des tissus sur les premiers millimètres du corps...

This article presents the mathematical model of the unconditionally stable explicit transmission-line matrix (USE-TLM) method, which can operate at a time step beyond the Courant–Friedrichs–Lewy (CFL) limit. This technique is based on the eigenmode decomposition of the system matrix that represents the computational domain. Then, by eliminating...
