Abstract At the physical level of rigour it is shown that there are no substantial theoretical arguments in favour using either plasma mode permittivity or Drude model Lifshitz formula. The decision this question rests with comparison calculations experiment. In course study derivation fluctuation–dissipation theorem proposed where displayed clear at which reasoning stage and what way dissipati...

We study the Drude weight D(T ) at finite temperatures T of an integrable bosonic model where the particles interact via nearest-neighbour coupling on a chain. At low temperatures, D(T ) is shown to be universal in the sense that this region is equivalently described by a Gaussian model. This lowtemperature limit is also relevant for the integrable one-dimensional Bose gas. We then use the ther...

Metasurfaces are artificial sheets with sub-wavelength thickness and they two-dimensional equivalents of metamaterials. The generalized sheet transition conditions (GSTCs) have been recently proposed for electromagnetic analysis the metasurfaces. In GSTCs, metasurface is generally modeled as a zero-thickness. However, conventional finite-difference time-domain (FDTD) method not straightforwardl...

We present a three-dimensional finite difference time domain (FDTD) method on graphics processing unit (GPU) for plasmonics applications. For the simulation of plasmonics devices, the Lorentz-Drude (LD) dispersive model is incorporated into Maxwell equations, while the auxiliary differential equation (ADE) technique is applied to the LD model. Our numerical experiments based on typical domain s...
