Analytical technique for subwavelength far field imaging
Sukosin Thongrattanasiri,Nicholas A. Kuhta,Matthew D. Escarra,Anthony J. Hoffman,Claire F. Gmachl,Viktor A. Podolskiy +5 more
TL;DR: In this article, an analytical technique for retrieving the size and shape of subwavelength objects using far-field measurements was developed, which can be used at any frequency range, and may become a practical alternative to scanning near-field microscopy.
Journal ArticleDOI
Structural second-order nonlinearity in plasmonic metamaterials
Brian Wells,Anton Yu. Bykov,Giuseppe Marino,Mazhar E. Nasir,Anatoly V. Zayats,Viktor A. Podolskiy +5 more
TL;DR: In this article, the authors demonstrate the emergence of a strong bulk second-order nonlinear response in a plasmonic nanorod composite comprised of centrosymmetric materials.

CoPhy-PGNN: Learning Physics-guided Neural Networks with Competing Loss Functions for Solving Eigenvalue Problems
Mohannad Elhamod,Jie Bu,Christopher N. Singh,Matthew Redell,Abantika Ghosh,Viktor A. Podolskiy,Wei-Cheng Lee,Anuj Karpatne +7 more
TL;DR: A novel approach to handle competing PG losses is presented and its efficacy in learning generalizable solutions in two motivating applications of quantum mechanics and electromagnetic propagation is demonstrated.
Journal ArticleDOI
Plasmon-enhanced absorption by optical phonons in metal-dielectric composites
M. Gadenne,Viktor A. Podolskiy,P. Gadenne,Ping Sheng,Vladimir M. Shalaev,Vladimir M. Shalaev,Vladimir M. Shalaev +6 more
TL;DR: In this article, the metal plasmon modes can strongly couple to the dielectric vibrational modes, optical phonons, leading to enhanced absorption of the phonons in Au − Al2O3 percolation composites.
Journal ArticleDOI
Low-threshold lasing and broad-band multiphoton-excited light emission from Ag aggregate-adsorbate complexes in microcavity
Vladimir P. Drachev,W. Kim,V. P. Safonov,Viktor A. Podolskiy,Nikolai Zakovryashin,Eldar Khaliullin,Vladimir M. Shalaev,Robert L. Armstrong +7 more
TL;DR: In this paper, a novel class of composites for optics, microcavities doped with metal fractal aggregates, is studied, where broad-band Stokes and anti-Stokes emission from (Ag colloidal aggregates)/(adsorbed molecules)/(micro-cavity) composite at low-intensity cw and pulse laser excitation has been found.
