Abstract
Simulation of electromagnetic and optical wave propagation in, e.g. water, fog or dielectric waveguides requires modeling of linear, temporally dispersive media. Using a POD-greedy and ID-greedy sampling driven by an error indicator, we seek to generate a reduced model which accurately captures the dynamics over a wide range of parameters, modeling the dispersion. The reduced basis model reduction reduces the model order by a factor of more than 20, while maintaining an approximation error of significantly less than 1% over the whole parameter range.
