Silicon substrate significantly alters dipole-dipole resolution in coherent microscope
Zicheng Liu, Krishna Agarwal
Influences of a substrate below samples in imaging performances are studied by reaching the solution to the dyadic Green's function, where the substrate is modeled as half space in…

Surrogate modeling based on resampled polynomial chaos expansions
Z. Liu, D. Lesselier, B. Sudret +1
In surrogate modeling, polynomial chaos expansion (PCE) is popularly utilized to represent the random model responses, which are computationally expensive and usually obtained by d…
