Measurement and Optimal Targeting of a Hidden Scatterer in a Complex Environment Utilizing Fisher Information
Nadav Shaibe, Jared Erb, Steven M. Anlage
A complex, non-Hermitian scattering system with a high degree of multiple scattering and interference is often treated as a black box, described simply by the relationship between…
Universal Frequency Correlations and Recurrence Statistics of Complex Impedance Matrices
Nadav Shaibe, Jared Erb, Thomas M. Antonsen +1
Linear electromagnetic wave scattering systems can be characterized by an impedance matrix that relates the voltages and currents at the ports of the system. When the system size b…
Superuniversal Statistics with Topological Origins for non-Hermitian Scattering Singularities
Nadav Shaibe, Jared M. Erb, Steven M. Anlage
Vortex singularities in speckle patterns formed from random superpositions of waves are an inevitable consequence of destructive interference and are consequently generic and ubiqu…
Robust Wave Splitters Based on Scattering Singularities in Complex non-Hermitian Systems
Jared Erb, Nadav Shaibe, Tsampikos Kottos +1
We have discovered specific conditions for generic scattering systems to act as wave splitters that are robust to any change in relative amplitude or phase of an arbitrary injected…
Novel Topology and Manipulation of Scattering Singularities in Complex non-Hermitian Systems
Jared Erb, Nadav Shaibe, Robert Calvo +4
The control of wave scattering in complex non-Hermitian settings is an exciting subject -- often challenging the creativity of researchers and stimulating the imagination of the pu…
Superuniversal Statistics of Complex Time-Delays in Non-Hermitian Scattering Systems
Nadav Shaibe, Jared M. Erb, Steven M. Anlage
The Wigner-Smith time-delay of flux conserving systems is a real quantity that measures how long an excitation resides in an interaction region. The complex generalization of time-…
