Stereographic coordinates for simpler far-field radiation analysis
Vassili Savinov
A coordinate system is proposed for the purposes of analysis of far-field radiation from a localized source at the origin. The proposed coordinates exhibit no singularities over th…
Toy model of harmonic and sum frequency generation in 2D nanostructures
Jie Xu, Vassili Savinov, Eric Plum
Optical nonlinearities of matter are often associated with the response of individual atoms. Here, using a toy oscillator model, we show that in the confined geometry of a two-dime…
Building blocks for space-time non-separable pulses
Apostolos Zdagkas, Nikitas Papasimakis, Vassili Savinov +1
Space-time non-separable pulses hold promise for topological information transfer, probing ultra-fast light-matter interactions and engaging toroidal excitations in matter. Spurred…
Infrared dielectric metamaterials from high refractive index chalcogenides
H. N. S. Krishnamoorthy, G. Adamo, J. Yin +3
High-index dielectric materials are in great demand for nanophotonic devices and applications, from ultrathin optical elements to metal-free sub-diffraction light confinement and w…
Unlabelled Far-field Deeply Subwavelength Superoscillatory Imaging (DSSI)
T. Pu, V. Savinov, G. Yuan +2
Recently it was reported that deeply subwavelength features of free space superoscillatory electromagnetic fields can be observed experimentally and used in optical metrology with…
Far-field radiation of electric and toroidal dipoles in loss-less non-magnetic dielectric medium with refractive index n
V. Savinov
Using simple classical treatment it is shown that the power emitted by the electric and toroidal dipoles scales differently with the refractive index of the surrounding environment…
