Abstract
A novel rational-fraction dispersion model is proposed for simulation
of optical properties of arbitrary linear dispersive media over a wide wavelength
range. A generally applicable method is proposed for estimating the parameters
of this model. It is demonstrated that the rational-fraction dispersion model
can fit the relative permittivity data of a material accurately and efficiently
in a wide wavelength range. The new model is implemented in the finite-difference
time-domain method and is applied as a powerful and computationally efficient
tool for simulating nano-particles of dispersive materials in a wide wavelength
range of light.
