Multipolar theory of bianisotropic response of meta-atoms
The bianisotropy of meta-atoms is usually associated with their nonlocal response and
mutual coupling between electric and magnetic dipole moments induced by an incident …

Multipolar expansions for scattering and optical force calculations beyond the long wavelength approximation
We review three different approaches for the calculation of electromagnetic multipoles,
namely, the Cartesian primitive multipoles, the Cartesian irreducible multipoles, and the …

Multipole interplay controls optical forces and ultra-directional scattering
We analyze the superposition of Cartesian multipoles to reveal the mechanisms underlying
the origin of optical forces. We show that a multipolar decomposition approach significantly …

Electromagnetic forces in the time domain
We look beyond the standard time-average approach and investigate optical forces in the
time domain. The formalism is developed for both the Abraham and Minkowski momenta …

Multipolar Pseudochirality-Induced Optical Torque
It has been observed that achiral nanoparticles, such as flat helices, may be subjected to an
optical torque even when illuminated by normally incident linearly polarized light. However …
