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…

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…
