Phys.org  November 2, 2023 Prominent non-Hermitian phenomena include coherent perfect absorption and its generalization, reflectionless scattering modes, in which electromagnetic scattering at the input ports is suppressed due to critical coupling with the power leaked to output ports, and interference phenomena. These concepts are ideally suited to enable real-time dynamic control over absorption, scattering and radiation. However, reflectionless scattering modes have not been observed in complex photonic platforms involving open systems and multiple inputs. An international team of researchers (USA – City University of New York, Germany) demonstrated the emergence of reflectionless scattering modes in a chaotic photonic microcavity involving […]
