We determine the channel state information (CSI) of a multiple-input single-output (MISO) Rayleigh channel without prior communications between the transmitting antennas and the receiver. Our approach solely relies on an impedance modulation at the r

In the diffusive transport regime, the mean path length of waves has been shown to be independent of the microstructure of the medium. Here, this invariance is shown to persist into the ballistic and localized regimes, as well as into the regime of b

An Interferometric Inverse SAR system is able to perform 3D imaging of non-cooperative targets by measuring their responses over time and through several receiving antennas. Phase differences between signals acquired with a spatial diversity in verti

The authors present a study of the modal contributions to the transmission matrix in a scattering medium. They show that the incident wave form can be manipulated to control the net energy deposited in the sample, as well as the energy deposited in a

The degree of nonorthogonality of eigenstates of non-Hermitian systems governs nuclear scattering, electronic conductance, and wave propagation in disordered media. Here, we determine the impact of non-Hermiticity upon eigenstates inside an open rand

The scattering of waves when they propagate through disordered media is an important limitation for a range of applications, including telecommunications

We study the coherence in time and space of electromagnetic fields propagated through complex media. Whether for localization, imaging or telecommunication, the development of dedicated numerical techniques is generally based on the exploitation of s
