Electromagnetic Scattering by a Cluster of Hybrid Dielectric-Plasmonic Dimers
Xinlin Cao, Ahcene Ghandriche, Mourad Sini
We consider time-harmonic electromagnetic scattering by a cluster of hybrid dielectric-plasmonic dimers in . Each dimer consists of a high-contrast dielectric nanopar…
Electromagnetic waves generated by a hybrid dielectric-plasmonic dimer
Xinlin Cao, Ahcene Ghandriche, Mourad Sini
We know that the electric field generated by a plasmonic nano-particle (with negative permittivity) is given as a polarization of the incident electric field. Similarly, the electr…
Effective Medium Theory for Heat Generation Using Plasmonics: A Parabolic Transmission Problem Driven by the Maxwell System
Xinlin Cao, Arpan Mukherjee, Mourad Sini
The excitation of plasmonic nanoparticles by incident electromagnetic waves at frequencies near their subwavelength resonances induces localized heat generation in the surrounding…
Optical Inversion Using Plasmonic Contrast Agents
Xinlin Cao, Ahcene Ghandriche, Mourad Sini
We describe a new method to reconstruct the permittivity distribution, of an object to image, from the remotely measured electromagnetic field. We propose to use the remote fields…
Effective medium theory for Van-Der-Waals heterostructures
Xinlin Cao, Ahcene Ghandriche, Mourad Sini
We derive the electromagnetic medium equivalent to a collection of all-dielectric nano-particles (enjoying high refractive indices) distributed locally non-periodically in a smooth…
