“…All the simulations described in this paper have been performed using the in-house FDTD code TEMSI developed at the XLIM laboratory. This software is able to handle a conformal mesh instead of a Cartesian grid as it is often the case with classical FDTD methods [6] . In addition to regular solving capability, TEMSI implements several interesting features helpful for VIRC characterization such as oblique thin wire modeling (implementing Holland formalism), conformal mesh and solver as well as OpenMP/MPI parallelization.…”

We introduce a novel simulation procedure devoted to the inner field evaluation of arbitrary-shape reverberation chambers especially well-suited for the analysis of Vibrating Intrinsic Reverberation Chambers (VIRC). The described method is based on conformal Finite-Difference in Time-Domain (FDTD) modeling to account for the rough surface geometry of the VIRC walls. On this point, we took full advantage of the meshing capability of the in-house numerical code TEMSI developped by XLIM. Performance criteria typically introduced to evaluate the overall efficiency of conventional reverberation chambers (RC) are extracted from the computed S 11 of a log-periodic antenna meshed within the under-study resonant cavity. Numerical outcomes demonstrate excellent agreement with experimental results in similar conditions.

“…In this article (which is an extension of [15]), we are presenting the process we have implemented in order to simulate a VIRC with the FDTD method using for the first time (to the best of our knowledge) a conformal mesh [16], [17] in order to model a realistic VIRC geometry. Moreover, in order to reproduce as faithfully as possible a real experimental setup implemented in VIRC, the antenna considered in the simulations is a log-periodic one, an antenna typically used in RC.…”

This article presents an original simulation procedure devoted to the simulation of arbitrary-shaped reverberation chambers especially well suited for the analysis of vibrating intrinsic reverberation chambers (VIRC). The described method is based upon conformal finite-difference in time-domain (FDTD) modeling in order to model the rough surface geometry of the VIRC walls. On this point, we take full advantage of the performance of our in-house numerical FDTD code called TEMSI-FD and of its associated conformal mesher. First, uncorrelated geometries of the VIRC under study have been generated in order to analyze its performance as a RC from the computed S 11 parameter of a log-periodic antenna. Second, correlated geometries have been generated in order to consider the continuous movement of the VIRC walls with a straightforward algorithm, each geometry being associated to a given instant. In both frequency and time domains, numerical outcomes demonstrate excellent agreement with experimental results available in the literature in similar conditions.
