Increasing contribution of stochastic methods in the characterization of complex systems: reverberation chamber and urban environment

Abstract : The use of stochastic approaches for the electromagnetic characterization of complex systems is illustrated in two cases that are reverberation chambers and urban environment. Several stochastic approaches are adopted in both cases, from a perturbative approach to the determination of distributions; the indications they provide as well as the associated requirements in terms of computation time or measurement complexity differ.
