The reflection time difference, the energy derivative of the phase difference between two reflection amplitudes, is a signed sum of Lorentzians centered at the S-matrix zeroes and can be read off from the unitary deficit under weak absorption.

abstract
The nonorthogonality of eigenfunctions over the volume of non-Hermitian systems determines the nature of waves in complex systems. Here, we show in microwave measurements of the transmission matrix that the non-Hermiticity of open random systems leads to enhanced modal excitation and strong correlation between modes. Modal transmission coefficients reach values comparable to the dimensionless conductance which may be much larger than unity. This is accompanied by strong negative correlation between modal speckle patterns ensuring that net transmission is never larger than the incident power.

Reflection Time Difference as a probe of S-matrix Zeroes in Chaotic Resonance Scattering
The reflection time difference, the energy derivative of the phase difference between two reflection amplitudes, is a signed sum of Lorentzians centered at the S-matrix zeroes and can be read off from the unitary deficit under weak absorption.
