Researchers routinely sense molecules by their infrared vibrational “fingerprint” absorption
resonances. In addition, the dominant handedness of chiral molecules can be detected by …

We derive a set of design requirements that lead to structures suitable for molecular circular
dichroism (CD) enhancement. Achirality of the structure and two suitably selected …

Optical metasurfaces consist of 2D arrangements of scatterers, and they control the
amplitude, phase, and polarization of an incidence field on demand. Optical metasurfaces …

Metasurfaces with bound states in the continuum (BICs) have proven to be a powerful
platform for drastically enhancing light–matter interactions, improving biosensing, and …

The accurate and efficient computation of the electromagnetic response of objects made
from artificial materials is crucial for designing photonic functionalities and interpreting …

Arrays of nanoparticles exploited in light scattering applications commonly only feature
either a periodic or a rather random arrangement of its constituents. For the periodic case …

The transition matrix, frequently abbreviated as T-matrix, contains the complete information
in a linear approximation of how a spatially localized object scatters an incident field. The T …

Predicting the optical response of macroscopic arrangements of individual scatterers is a
computational challenge because the problem involves length scales across multiple orders …

The T-matrix is a powerful tool that provides the complete description of the linear interaction
between the electromagnetic field and a given object. In here, we generalize the usual …

Conventional optical diffusers, such as thick volume scatterers (Rayleigh scattering) or
microstructured surface scatterers (geometric scattering), lack the potential for on‐chip …
