“…The solutions to make time-domain simulations of RCs are based on transmission line matrix (TLM) [4] or finite differences time domain (FDTD) [5], [6], [7]. These methods use a space-time discretization of an electrically large and highly conductive environment and are complicated to perform.…”

6 pages - WOSInternational audienceIn this article, we propose a time-domain model of a reverberation chamber (RC). This very straightforward model based upon image theory (IT) allows to simulate the behavior of a reverberation chamber in the pulse regime. After a brief introduction of the model, results with different pulse lengths and different loading configurations are presented and compared to measurements made in the reverberation chamber of our laboratory

“…Therefore, techniques to accelerate simulating the lossy model are necessary. A feasible loss implementation has been presented in [4], which involves a multiplication between the impulse response of a lossless chamber and a exponentially damped window function based on the -factor. It should be noted that it is valid when the excitation is an impulse.…”

Aiming at accelerating the simulation of the lossy reverberation chamber using the finite-difference time-domain method, a fast and accurate approach is proposed. The lumped losses of the real chamber are equivalently substituted by adding the artificial-loss atmosphere, which is evenly distributed throughout the chamber. Unlike the lumped loss, such even loss could reduce the simulation time dramatically. The conductivity of such medium is evaluated on the basis of the quality factor of the reverberation chamber, which is generally deemed as the capability of composite losses, rather than by manual attempts or experience. As examples, two different sorts of excitations are simulated to validate the correctness and generality of the artificial-loss technique.

“…For broadband analysis, time-domain methods, such as the finite-difference time domain (FDTD) method [1] and the transmission-line matrix method [2], can be employed when the numerical modeling process is modified appropriately [3]- [7]. If no broadband results are required, frequency-domain methods, such as the finite-element method (FEM) [8] and the boundary element method (BEM) [9], also referred to as method of moments (MoM), can advantageously be used.…”

A novel boundary element method approach with the rectangular cavity Green's function is presented and utilized to model reverberation chambers. Different from all other approaches that employ rectangular cavity Green's functions, the computationally expensive part of the matrix-vector product is evaluated in the spectral domain. A drastic acceleration is achieved even though the algorithm operates with excellent accuracy. The approach is validated and compared against the boundary element method with free-space Green's function. Examples demonstrate the usability of the proposed approach.
