Intuitive understanding of extinction of small particles in absorbing and active host media within the MLWA
Anton D. Utyushev, Vadim I. Zakomirnyi, Alexey A. Shcherbakov +2
In an absorbing or an active host medium characterized by a complex refractive index , our previously developed modified dipole long-wave approximation (MLWA…
Large fluorescence enhancement via lossless all-dielectric spherical mesocavities
Vadim I. Zakomirnyi, Alexander Moroz, Rohit Bhargava +1
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, all-diel…
Remarkable Predictive Power of the Modified Long Wavelength Approximation
Ilia L. Rasskazov, Vadim I. Zakomirnyi, Anton D. Utyushev +2
The modified long-wavelength approximation (MLWA), a next order approximation beyond the Rayleigh limit, has been applied usually only to the dipole contribution and for t…
An atomistic description of alloys and core shells nanoparticles
Lasse K. Sørensen, Anton D. Utyushev, Vadim I. Zakomirnyi +1
Using the extended discrete interaction model we investigate the tuneabilty of surface plasmon resonance in alloys and core-shell nanoparticles made from silver and gold. We show t…
Plasmonic lattice Kerker effect in UV-Vis spectral range
V. S. Gerasimov, A. E. Ershov, R. G. Bikbaev +7
Mostly forsaken, but revived after the emergence of all-dielectric nanophotonics, the Kerker effect can be observed in a variety of nanostructures from high-index constituents with…
Ultra-narrowband selective tunable filters for visible and infrared wavelength ranges
A. D. Utyushev, I. L. Isaev, V. S. Gerasimov +6
The interaction of non-monochromatic radiation with two types of arrays comprising both plasmonic and dielectric nanoparticles has been studied in detail. We have shown that dielec…
