Based on an analytic approach, we present a theoretical review on the absorption,
scattering, and extinction of both dipole scatterers and regular arrays composed of such …

Electromagnetic forces and torques enable many key technologies, including optical
tweezers or dielectrophoresis. Interestingly, both techniques rely on the same physical …

The multipole expansion is a key tool in the study of light–matter interactions. All the
information about the radiation of and coupling to electromagnetic fields of a given charge …

The multipolar decomposition of electromagnetic sources is an important tool for the study of
light–matter interactions in general, and optical materials in particular. Here, a report is given …

Undoubtedly, laser tweezers are the most recognized application of optically induced
mechanical action. Their operation is usually described in terms of conservative forces …

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

Circularly polarized light carries spin angular momentum, so it can exert an optical torque on
the polarization-anisotropic particle by the spin momentum transfer. Here, we show that …

Metasurfaces made from densely packed resonant wavelength-scale particles enable
abrupt modulation of impinging electromagnetic radiation within an ultrathin surface …

Modern nanophotonic and meta-optical devices utilize a tremendous number of structural
degrees of freedom to enhance light–matter interactions. A fundamental question is how …

We propose novel quantum antennas and metamaterials with a strong magnetic response at
optical frequencies. Our design is based on the arrangement of natural quantum emitters …
