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…
Chirped Pulse Analysis and Control in Non-Hermitian Scattering Systems using Complex Time Delay
Isabella L. Giovannelli, Steven M. Anlage, Thomas M. Antonsen
We theoretically and experimentally establish a connection between linearly chirped pulse propagation properties and the complex generalization of Wigner-Smith time delay for both…
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…
A Physical Interpretation of Imaginary Time Delay
Isabella L. Giovannelli, Steven M. Anlage
The scattering matrix linearly relates the vector of incoming waves to outgoing wave excitations, and contains an enormous amount of information about the scattering system and…
