We present wave-based signal differentiation with unprecedented fidelity and flexibility by
purposefully perturbing overmoded random scattering systems such that zeros of their …

The scattering of waves when they propagate through disordered media is an important
limitation for a range of applications, including telecommunications, biomedical imaging …

We demonstrate experimentally that reflectionless scattering modes (RSMs), a generalized
version of coherent perfect absorption, can be functionalized to perform reflectionless …

Accessing subwavelength information about a scene from the far-field without invasive near-
field manipulations is a fundamental challenge in wave engineering. Yet it is well …

Leveraging topological properties in the response of electromagnetic systems can greatly
enhance their potential. Although the investigation of singularity‐based electromagnetics …

Hybrid quantum systems based on magnons in magnetic materials have made significant
progress in the past decade. They are built based on the couplings of magnons with …

A thorough understanding of the topological classifications of non-Hermitian energy bands
is essential for advancing non-Hermitian band theory and its applications. As evidenced in …

We investigate experimentally and analytically the coalescence of reflectionless (RL) states
in symmetric complex wave-scattering systems. We observe RL exceptional points (EPs) …

Wavefront shaping (WFS) has emerged as a powerful tool to control the propagation of
diverse wave phenomena (light, sound, microwaves, etc.) in disordered matter for …

We introduce a complex generalization of the Wigner time delay τ for subunitary scattering
systems. Theoretical expressions for complex time delays as a function of excitation energy …
