Purpose The majority of first-principle, homogenisation techniques makes use of the dipole terms of a small particle radiation, and, consequently, the respective dipole polarisabilities. This paper aims to take the next step and propose a new systema

Optical metasurfaces consist of a 2D arrangement of scatterers, and they control the amplitude, phase, and polarization of an incidence field on demand. Optical metasurfaces are the cornerstone for a future generation of flat optical devices in a wid

Quasi bound states in the continuum (quasi-BICs) are expected to trigger significant advances in sensing and non-linear optics. Here, we perform a higher-order multipolar analysis of an all-dielectric metasurface that sustains a quasi-BIC resonance.

Metasurfaces based on quasi-bound states in the continuum (quasi-BICs) constitute an emerging toolkit in nanophotonic sensing as they sustain high quality factor resonances and substantial near-field enhancements. It is demonstrated that silicon meta

The wavenumbers for an obliquely propagating transverse electromagnetic mode via a 3-D array of anisotropic scatterers are theoretically studied and numerically derived through a consistent method based on the dipole approximation. First, it is assum

In this work, while exploiting the latest multiple scattering software that can handle up to a million of particles, we explore the possibility to observe Anderson localization of light in a disordered medium. The proposed method is an excellent tool

Hierarchical plasmonic–photonic microspheres (PPMs) with high controllability in their structures and optical properties have been explored toward surface-enhanced Raman spectroscopy. The PPMs consist of gold nanocrystal (AuNC) arrays (3rd-tier) an
