Applying the resonant-state expansion to realistic materials with frequency dispersion
Hame Sehmi, Wolfgang Langbein, Egor Muljarov
The dispersive resonant-state expansion, developed for an accurate calculation of the resonant states in open optical systems with frequency dispersion, is applied here to realisti…
How to calculate the pole expansion of the optical scattering matrix from the resonant states
T. Weiss, E. A. Muljarov
We present a formulation for the pole expansion of the scattering matrix of open optical resonators, in which the pole contributions are expressed solely in terms of the resonant s…
Resonant-state expansion of three-dimensional open optical systems: Light scattering
S. V. Lobanov, W. Langbein, E. A. Muljarov
A rigorous method of calculating the electromagnetic field, the scattering matrix, and scattering cross-sections of an arbitrary finite three-dimensional optical system described b…
Optimizing the Drude-Lorentz model for material permittivity: Examples for semiconductors
Hame S Sehmi, Wolfgang Langbein, Egor A Muljarov
Approximating the frequency dispersion of the permittivity of materials with simple analytical functions is of fundamental importance for understanding and modeling their optical p…
