Robust Adaptive Least Squares Polynomial Chaos Expansions in High-Frequency Applications
Dimitrios Loukrezis, Armin Galetzka, Herbert De Gersem
We present an algorithm for computing sparse, least squares-based polynomial chaos expansions, incorporating both adaptive polynomial bases and sequential experimental designs. The…
Adaptive Sparse Polynomial Chaos Expansions via Leja Interpolation
Dimitrios Loukrezis, Herbert De Gersem
This work suggests an interpolation-based stochastic collocation method for the non-intrusive and adaptive construction of sparse polynomial chaos expansions (PCEs). Unlike pseudo-…
Influence of spatial dispersion on surface plasmons, nanoparticles and grating couplers
Armel Pitelet, Emmanuel Centeno, Antoine Moreau +5
Recent experiments have shown that spatial dispersion may have a conspicuous impact on the response of plasmonic structures. This suggests that in some cases the Drude model should…
Approximation and Uncertainty Quantification of Systems with Arbitrary Parameter Distributions using Weighted Leja Interpolation
Dimitrios Loukrezis, Herbert De Gersem
Approximation and uncertainty quantification methods based on Lagrange interpolation are typically abandoned in cases where the probability distributions of one or more {system} pa…
