Dispersive Effective Metasurface Model for Bubbly Media
Arpan Mukherjee, Mourad Sini
We derive the effective transmission condition for a cluster of acoustic subwavelength resonators, modeled as small-scaled bubbles distributed not necessarily periodically along a…
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…
Dispersive Effective Model in the Time-Domain for Acoustic Waves Propagating in Bubbly Media
Arpan Mukherjee, Mourad Sini
We derive the effective medium theory for the linearized time-domain acoustic waves propagating in a bubbly media. The analysis is done in the time-domain avoiding the need to use…
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…
Electromagnetic waves generated by a dielectric moving at a constant speed
Manas Kar, Mourad Sini
We consider a regular and bounded dielectric body moving at a speed , following a constant vector field , with respect to a reference frame. In this frame, the special rela…
