Poláritons magnéticos em meio giromagnético com camada de grafeno
(Universidade Federal do Rio Grande do NorteBrasilUFRNPROGRAMA DE PÓS-GRADUAÇÃO EM FÍSICA, 2021-04-09)
In this work we present the theoretical study on magnetic polaritons (magnon-polaritons)
in a system formed by a semi-infinite gyromagnetic medium (ferromagnetic or antiferromagnetic), with a layer of graphene at the ...
A long-range surface plasmon-polariton waveguide ring resonator as a platform for (bio)sensor applications
(Institute of Physics - IOPBristol, 2011-11)
Dispersive characteristics of surface plasmon polaritons on negative refractive index gratings
(Elsevier Science, 2011-10)
The dispersive characteristics of surface plasmon polaritons (SPPs) supported by a periodically corrugated boundary between vacuum and a negative refractive index, isotropic material were studied theoretically by numerical ...
Phase and reflectivity behavior near the excitation of surface plasmon polaritons in Kretschmann-ATR systems with metamaterials
(Springer, 2012-01)
In this work we study the optical response of Kretschmann-ATR structures with metamaterials near conditions of resonant coupling between the incident wave and a surface plasmon polariton. In contrast with previous research ...
Polaritons in modified antiferromagnets
(American Physical Society, 1992-11-01)
A theoretical study of mixed modes of uniaxial Heisenberg antiferromagnets by a dc field is presented. The static field is applied in an arbitrary direction relative to the easy axis and special attention is given to the ...
Near field evidence of backward surface plasmon polaritons on negative index material boundaries
(Elsevier Science, 2016-12)
We present a detailed analysis about the electromagnetic response of a metamaterial surface with a localized defect. The excitation of electromagnetic surface waves leads to a near-field distribution showing a periodic ...
Scattering of a surface plasmon polariton by a localized dielectric surface defect
(Optical Society of America, 2013-04)
On the basis of a rigorous, nonperturbative, purely numerical
solution of the corresponding reduced Rayleigh equation for the scattering
amplitudes we have studied the scattering of a surface plasmon polariton
by a two ...
Dipole modelling for a robust description of subdiffractional polariton waves
(2019-11-28)
The nanophotonics of van der Waals (vdW) materials relies critically on the electromagnetic properties of polaritons defined on sub-diffraction length scales. Here, we use a full electromagnetic Hertzian dipole antenna ...
Polaritons de exciton em super-redes semicondutoras
(Universidade Federal do Rio Grande do NorteBRUFRNPrograma de Pós-Graduação em FísicaFísica da Matéria Condensada; Astrofísica e Cosmologia; Física da Ionosfera, 2004-12-03)
In this work we study the spectrum (bulk and surface modes) of exciton-polaritons in infinite and semi-infinite binary superlattices (such as, ···ABABA···), where the semiconductor medium (A), whose dielectric function ...
