Article
Photoinduced voltages associated with surface plasmon polariton excitations are studied both theoretically and experimentally in various plasmonic systems as the function of material, wavelength, and type of structure. Experimental photovoltage normalized to the absorbed power shows a general decrease upon an increase in the wavelength, enhancement...

We introduce a theory of optical responses of bianisotropic layers with arbitrary effective medium parameters, which results in generalized Fresnel-Airy equations for reflection and transmission coefficients at all incidence directions and polarizations. The poles of these equations provide explicit expressions for the dispersion of Fabry-Perot res...

Conference Paper
Plasmonic structures provide possibilities to control and enhance spontaneous emission, including emission, at weak magnetic transitions, which is of interest for various applications. However, quenching in metal via near field excitations may present significant problems. In our work, we compare systems with dense and dilute arrangement of emitter...

Significant photoinduced DC electrical effects (currents and potentials) observed in metal films and nanostructures are promising for various applications and present interest from the fundamental physics perspective. They are clearly associated with plasmon excitations, and are the result of strong fields and high field gradients of strongly confi...

We describe novel topological phases of isofrequency k-space surfaces in bianisotropic optical materials—tri- and tetrahyperbolic materials—which are induced by the introduction of chirality. This completes the classification of isofrequency topologies for bianisotropic materials, as we showed that all optical materials belong to one of the followi...

We describe novel topological phases of iso-frequency k-space surfaces in bi-anisotropic optical materials - tri- and tetra-hyperbolic materials, which are induced by introduction of chirality. This completes the classification of iso-frequency topologies for bi-anisotropic materials, since as we show all optical materials belong to one of the foll...
Preprint
We explore coupling of plasmonic, electric and magnetic effects in profile modulated permalloy structures, which have both plasmonic properties and uniaxial magnetic anisotropy with an in-plane easy axis. Strong photocurrents, observed under plasmon resonance conditions, show a clear dependence on the magnetic field with a characteristic hysteresis...
Article
The spontaneous emission of weak magnetic dipoles located in the vicinity of a plasmonic metal is analyzed theoretically and studied experimentally using Eu3+ ions in organic matrices as a spectroscopic probe. We show that close distances to metal are preferable for magnetic light enhancement experiments, as magnetic dipoles show weaker quenching t...
Article
A previous presentation compared acoustical and optical resonances of a Mie regime double sphere system that focused on a side scattering phenomenon that roughly mimicked a mirror [C. E. Dean and R. M. Hodges, JASA, 143, 1844 (2018)]. If one thinks of these scatterers as lenses the presence of a photonic or phononic “jet” suggests a caustic region...
Article
Additional electromagnetic waves and additional boundary conditions (ABCs) in non-local materials attract a lot of attention. Here we report the possibility of additional propagating and evanescent waves in local anisotropic and bi-anisotropic linear materials if non-reciprocity is present. We also show that additional waves cannot propagate in loc...

We propose a general and complete classification of all possible new and old kinds of surface plasmon polaritons (SPPs) that can propagate at boundaries of arbitrary linear, local bi-anisotropic media, including the quartic metamaterials. In particular, we introduce a new kind of generic bi-exponential SPPs with arbitrary frequency, wavelength, pro...

Conference Paper
Photoinduced voltages in profile-modulated plasmonic surfaces demonstrate sharp dependence on the incidence angle and are very sensitive to dielectric environment, which provides opportunities for applications in compact plasmonic sensors with electrical detection.
Conference Paper
We study the short-wavelength waves in quartic metamaterials. The quartic k-surfaces feature from 0 to 4 cones, longitudinal polarization E,H ‖ k and perpendicular to k group velocities, which leads to negative refraction in quartic metamaterials.
Article
We propose an approach to engineer quartic metamaterials starting from the desired photonic states. We apply our method to the design of the high-k asymptotics of metamaterials, extreme non-reciprocity and complex bi-anisotropic media.
Article
We show that spin angular momentum (SAM) of light is transferred to matter together with momentum and energy, and obtain the expression for the corresponding torque. This can lead to appearance of spin forces, which correspond to the discrepancy between the Lorentz and Einstein-Laub forces. In plasmonic metals these spin forces result in a plasmoga...
Article
Excitation of collective plasmonic modes and their effect on optical behavior are experimentally and theoretically studied in 1D arrays of gold nanostrips in comparison with continuous gold films with periodically modulated profile. In strips, the angular dependence of the reflectivity demonstrates a peak at the resonance condition as opposed to a...
Chapter
The plasmon drag effect was discovered about a decade ago in 2005. Since then, it has attracted considerable attention from the nanotechnology and photonics community due to fundamental physics of this effect as manifestation of electron plasmon coupling and myriad of possible applications in nanoelectronics, photonics and sensing. In this chapter,...

We introduce the continuity equation for the electromagnetic spin angular momentum (SAM) in matter and discuss the effects of the SAM transfer to materials. The corresponding torque can be represented using spin forces, which we describe in this manuscript. We show that the spin forces are expected to result in pinning the plasmon drag effect or pl...
Article
We show that it is possible to design an invisible wavelength-sized metal-dielectric metamaterial object without evoking cloaking. Our approach is an extension of the neutral inclusion concept by Zhou and Hu [Phys.Rev.E 74, 026607 (2006)] to Mie scatterers. We demonstrate that an increase of metal fraction in the metamaterial leads to a transition...

The electromagnetic momentum loss approach is applied to predict the plasmon drag effect in profile-modulated gold films at different amplitudes of surface modulations. Direct proportionality of energy and momentum transfer in interactions of plasmons and free electrons in metal is proven to be valid for surfaces with relatively low height modulati...

Light-matter momentum transfer in plasmonic materials is theoretically discussed in the framework of a plasmonic pressure mechanism taking into account nonequilibrium electron dynamics and the thermalization process. We show that our approach explains the experimentally observed relationship between the plasmon-related electromotive force and the a...

Plasmon drag effect is studied theoretically and experimentally in gold films with a sine-wave height profile. Numerical simulations based on the modified electromagnetic momentum loss approach are shown to correctly describe the photoinduced voltage associated with propagating surface plasmon polaritons. Direct proportionality of energy and moment...

Gold nanostrip arrays exhibit collective plasmonic oscillations analogous to surface plasmon-polaritons in continuous films with a spatially modulated profile. Similarities and differences in optical behavior of continuous and discontinuous systems are studied experimentally and theoretically.
Conference Paper
The proposed hot-electron-mediated plasmonic pressure model explains the observed relationship between plasmon drag emf and absorption, emphasizes its quantum plasmonics nature and allows for correct calculation of the emf in metal for the first time.
Article
Optical properties of a metasurface which can be considered a monolayer of two classical uniaxial metamaterials, parallel-plate and nanorod arrays, are investigated. It is shown that such metasurface acts as an ultimately thin sub-50 nm wave plate. This is achieved via an interplay of epsilon-near-zero and epsilon-near-pole behavior along different...
Conference Paper
Plasmonics is promising for future electronics as it can combine optical speed of operation with nanoscale size, something which is not possible with traditional optics and electronics [1]. Coupling of photons, plasmonic excitations and electrons is of key importance as it provides opportunities to monitor or control plasmonic nanocircuits electric...

Optical fields in metamaterial nanostructures can be separated into bright modes, whose dispersion is typically described by effective medium parameters, and dark fluctuating fields. Such combination of propagating and evanescent modes poses a serious numerical complication due to poorly conditioned systems of equations for the amplitudes of the mo...

We propose a new class of optical resonator structures featuring one or two metasurface reflectors or metacavities and predict that such resonators support novel hyperbolic resonances. As an example of such resonances we introduce hyperbolic Tamm plasmons (HTPs) and hyperbolic Fabry-Perot resonances (HFPs). The hyperbolic optical modes feature low-...

Strong modification of spontaneous emission of Eu3+ ions placed in close vicinity to thin and thick gold and silver films was clearly demonstrated in a microscope setup separately for electric and magnetic dipole transitions. We have shown that the magnetic transition was very sensitive to the thickness of the gold substrate and behaved distinctly...
Article
Full-text available
We propose a novel photonic structure composed of metal nanolayer, Bragg mirror and metal nanolayer. The structure supports resonances that are transitional between Fabry-Perot and Tamm modes. When the dielectric contrast of the DBR is removed these modes are a pair of conventional Fabry-Perot resonances. They spectrally merge into a Tamm mode at h...

We predict a dynamic metallization effect where an ultrafast (single-cycle) optical pulse with a $$\lesssim${}1\text{ }\text{ }\mathrm{V}/\AA{}$ field causes plasmonic metal-like behavior of a dielectric film with a few-nm thickness. This manifests itself in plasmonic oscillations of polarization and a significant population of the conduction band...

We introduce an effect of metallization of dielectric nanofilms by strong, adiabatically varying electric fields. The metallization causes optical properties of a dielectric film to become similar to those of a plasmonic metal (strong absorption and negative permittivity at low optical frequencies). This is a quantum effect, which is exponentially...

We present a systematic investigation into the conditions required for the production of XUV light via nanoplasmonic enhanced high harmonic generation in metallic spheroids. Control over the temporal response of the plasmonic fields, and therefore the resulting XUV radiation, is achieved through the nanostructure configuration and the carrier envel...

In this Letter we develop a theory of spoof plasmons propagating on real metals perforated with planar periodic grooves. Deviation from the spoof plasmons on perfect conductor due to finite skin depth has been analytically described. This allowed us to investigate important propagation characteristics of spoof plasmons such as quality factor and pr...

We establish the principal limits for the nanoconcentration of the THz radiation in metal/dielectric waveguides and determine their optimum shapes required for this nanoconcentration. We predict that the adiabatic compression of THz radiation from the initial spot size of R(0) approximately lambda(0) to the final size of R = 100- 250 nm can be achi...

In this paper, we propose a general and powerful theory of the plasmonic enhancement of the many-body phenomena resulting in a closed expression for the surface plasmon-dressed Coulomb interaction. We illustrate this theory by computing the dressed interaction explicitly for an important example of metal–dielectric nanoshells which exhibits a rich...

We introduce an approach to implement full coherent control on nanometer length scales. It is based on spatiotemporal modulation of the surface plasmon polariton (SPP) fields at the thick edge of a nanowedge. The SPP wavepackets propagating toward the sharp edge of this nanowedge are compressed and adiabatically concentrated at a nanofocus, forming...
