The newly emerging field of wave front sha** in complex media has recently seen
enormous progress. The driving force behind these advances has been the experimental …

The absorption of electromagnetic energy by a material is a phenomenon that underlies
many applications, including molecular sensing, photocurrent generation and …

Magnon–polaritons are hybrid light–matter quasiparticles originating from the strong
coupling between magnons and photons. They have emerged as a potential candidate for …

The scattering of electromagnetic waves lies at the heart of most experimental techniques
over nearly the entire electromagnetic spectrum, ranging from radio waves to optics and x …

Bound states in the continuum (BICs) are resonant modes of open structures that do not
suffer dam**, despite being compatible with radiation in terms of their momentum. They …

Perfect absorbers, which can achieve total absorption of all incoming energy, have been
extensively studied in the last decades for various important technologies in general wave …

Effective non-Hermitian Hamiltonians are obtained to describe coherent perfect absorbing
and lasing boundary conditions. PT symmetry of the Hamiltonians enables us to design …

Enhancement of light-matter interactions is of great importance for many nanophotonic
devices, and one way to achieve it is to feed energy perfectly to the strongly coupled system …

Near‐complete absorption of light has the potential to underpin advances in photodetection,
advanced chemistry, coloration of materials, and energy. This review paper reports recent …
