Super-Resonance: Interference-Driven Suppression of Radiative Decay Across Wave Physics
Igor V. Minin, Oleg V. Minin, Ilia L. Rasskazov
Super-resonance has been coined independently for collective modes of acoustic cavity arrays (Tolstoy), extreme high- states of dielectric resonators in photonics, and magnon-po…
Scattering correction for infrared spectra of biological cells using computational infrared microspectroscopy and deep learning
Sergio G. Rodrigo, Ilia L. Rasskazov, Luis Martin-Moreno +1
IR microspectroscopy of single biological cells is challenged by strong light scattering, which produces baseline effects and peak distortions in the IR spectra and hinders the dir…
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…
Generation of nearly pure and highly directional magnetic light in fluorescence of rare earth ions
Anton D. Utyushev, Roman Gaponenko, Song Sun +3
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…
Experimental demonstration of superdirective spherical dielectric antenna
Roman Gaponenko, Mikhail S. Sidorenko, Dmitry Zhirihin +5
An experimental demonstration of directivities exceeding the fundamental Kildal limit, a phenomenon called superdirectivity, is provided for spherical high-index dielectric antenna…
Metal-Dielectric-Enhanced Upconversion: Going "Meso"
Ilia L. Rasskazov, Alexander Moroz, Catherine J. Murphy +2
A novel concept of a \textit{mesocavity}, based on a simple yet counter-intuitive idea of covering metal nanoparticles with unusually thick ( nm) high-index dielectric…
Is there a proper figure of merit for a plasmonic structure involved in metal-enhanced fluorescence?
Ilia L. Rasskazov, Alexander Moroz
A suitability of a nanostructure for a metal-enhanced fluorescence (MEF) is usually assessed from the value of the maximal fluorescence enhancement factor, , which it…
Excitation of a homogeneous dielectric sphere by a point electric dipole
Roman Gaponenko, Ilia L. Rasskazov, Alexander Moroz +3
Electrically small dielectric antennas are of great interest for modern technologies, since they can significantly reduce the physical size of electronic devices for processing and…
Harnessing superdirectivity in dielectric spherical multilayer antennas
Roman Gaponenko, Alexander Moroz, Ilia L. Rasskazov +3
Small form-factor, narrowband, and highly directive antennas are of critical importance in a variety of applications spanning wireless communications, remote sensing, Raman spectro…
Extraordinary fluorescence enhancement in metal-dielectric core-shell nanoparticles
Ilia L. Rasskazov, Alexander Moroz, P. Scott Carney
Contrary to a paradigm of metal-enhanced fluorescence, unusually thick dielectric coatings can be very favorable to achieve extreme values of averaged fluorescence enhancement fact…
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…
