Summary

Complex topological edge modes in non-Hermitian systems can cause anomalous scattering. This phenomenon, observed in gain-coated resonators, may lead to undetectable information leakage in communication channels.

Area of Science:

  • Physics
  • Optical Engineering
  • Quantum Mechanics

Background:

  • Topological edge modes are robust in Hermitian systems.
  • Non-Hermitian systems can exhibit complex-frequency modes.
  • Hermitian symmetry is crucial for understanding topological phenomena.

Purpose of the Study:

  • Investigate the behavior of topological edge modes in non-Hermitian systems.
  • Explore the potential for anomalous scattering from complex topological edge modes.
  • Propose a practical realization for observing this scattering phenomenon.

Main Methods:

  • Analytical two-band model for theoretical prediction.
  • Multiple-multipole scattering theory for numerical simulations.
  • Design of a linear array of subwavelength resonators with gain media.

Main Results:

  • Complex topological edge modes exhibit negligible forward optical extinction.
  • Simultaneous excitation of these modes leads to anomalous sideway scattering.
  • The proposed resonator array demonstrates this predicted scattering behavior.

Conclusions:

  • Non-Hermitian systems can host novel topological phenomena like anomalous scattering.
  • This scattering effect could enable stealthy information transfer in optical communication.
  • The findings have implications for secure classical information transmission.
