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

We experimentally generate and characterize eigenstates of the Wigner-Smith time-delay
matrix, called principal modes, in a multimode fiber with strong mode coupling. The unique …

We present experimental and numerical studies on principal modes in a multimode fiber
with mode coupling. By applying external stress to the fiber and gradually adjusting the …

Understanding vanishing transmission in Fano resonances in quantum systems and
metamaterials and perfect and ultralow transmission in disordered media has advanced the …

Dynamic and steady-state aspects of wave propagation are deeply connected in lossless
open systems in which the scattering matrix is unitary. There is then an equivalence among …

The transmission matrix is a unique tool to control light through a scattering medium. A
monochromatic transmission matrix does not allow temporal control of broadband light …

The quantum conductance and its classical wave analogue, the transmittance, are given by
the sum of the eigenvalues of the transmission matrix. However, neither measurements nor …

Selective excitation of a diffusive system's transmission eigenchannels enables
manipulation of its internal energy distribution. The fluctuations and correlations of the …

Transmission through disordered samples can be controlled by illuminating a sample with
waveforms corresponding to the eigenchannels of the transmission matrix (TM). But can the …

The degree of nonorthogonality of eigenstates of non-Hermitian systems governs nuclear
scattering, electronic conductance, and wave propagation in disordered media. Here, we …
