Large-scale simulations are performed by means of the transfer-matrix method to reveal
optimal conditions for metal–dielectric core–shell particles to induce the largest fluorescence …

The present paper pursues a fairly usual tradition basically devoted to reviews describing
advances in some light scattering theories in which the illuminating beam is described using …

We present a computer code for calculating near-and far-field electromagnetic properties of
multilayered spheres. STRATIFY is a one-of-a-kind open-source package that allows for …

In this work, a novel approach for enhancing magnetic fields in all‐dielectric nanoantennas
using Spherical Bragg Resonators (SBR) is proposed, which can boost quantum emitters' …

We show that in metal-dielectric core–shell nanoparticles, unusually thick dielectric coatings
can produce extreme fluorescence enhancement with an enhancement factor F̅≳ 3000 for …

This work reports experimental investigation and numerical validation of millimeter-sized
Spherical Bragg Resonators (SBRs) fabricated using 3D printing technology. The frequency …

A thorough analysis of the emission via the magnetic dipole (MD) transition, called magnetic
light below, of trivalent rare-earth ions in or near dielectric homogeneous spheres has been …

An experimental demonstration of directivities exceeding the fundamental Kildal limit, a
phenomenon called superdirectivity, is provided for spherical high-index dielectric antennas …

An efficient progressive methodology is presented for the computation of multi-scattering of
electromagnetic waves by a multilayered concentric nanoparticle. Instead of solving a large …

Nano-and microparticles are popular media to enhance optical signals, including
fluorescence from a dye proximal to the particle. Here we show that homogeneous, lossless …
