Modeling and simulation of active plasmonics with the FDTD method by using solid state and Lorentz–Drude dispersive model

Beam focusing with a wide range of focal length from a single slit surrounded by Ag–SiO2–Ag multilayer gratings

“…In the simulations, the dielectric function of Ag is described by the Lorentz-Drude (LD) model [13], which has been demonstrated that the optical parameters of various metals (include Ag) in the LD model is in good agreement with Palik data [9,14,15]:…”

Simulation of active microdisk antenna using solid state and dispersive models

“…The frequency dependent permittivity is treated by LorentzDrude model, and can be made consistent with time domain Maxwell equations by using the auxiliary differential equation (ADE) approach [10]. After using LD model in equation (1) and then by applying the ADE approach following equation are obtained …”

“…In this paper, the FDTD method is used due to its simplicity and generality. For the modeling of metallic nanorods LD model and for the modeling of semiconductor a solid state model that includes Pauli Exclusion Principle, state filling and dynamical Fermi-Dirac thermalization [10] are used in Maxwell equations.…”

Simulation of Plasmonics Nanodevices with Coupled Maxwell and Schrödinger Equations using the FDTD Method

“…The f irst one is mor e suitable for information transmission rela ted applications, w hile th e second one is preferable for se nsing ap plications. A w ide range of plasmonic devices have been simulated, fabricated and characterized [1][2][3][4][5][6][7][8][9][10]. Some interesting results show that the surface plasmon polariton has strong analogy to Young's double-slit experiment and is discussed in [4].…”

“…The concept of semiconductor plasmonics using a so lid state model that includes Pauli exculsion principle, state filling effect, FermiDirac t hermalization, an d externa l magnetic fie ld is presented in [5]. A n umerical approach that consists of solid state and Lorentz-Drude m odels is presented t o simul ate active plasmonics devices [6]; and it is also used to simulate a plasm onic source , and t hen l ight ex traction from t he source [7]. S ome othe r active plasmonic de vices such a s Plas-MOStor (pla smonic based trans istor), ultrafa st a ctive devices, pa ssive a nd ac tive photonics c ircuits using S PP have be en r eported in [8-1 0].…”
