Resumen
Descripción
A new formulation for developing surrogate models
using polynomial-based functional interpolants is proposed in
this work. Our formulation starts from a zero-order model that
can be as simple as a fixed fine model response (for cases where a
continuous coarse model is not available), or it can also be a
simple linear input mapped coarse model. This zero-order model
is enhanced by multidimensional polynomial interpolants around
a central base point in the design space. The polynomial
approximation is a low-order function of the design variables,
and it is used to interpolate highly accurate electromagnetic
responses in a region of interest around the selected central base
point. Global optimal values for the surrogate model weighting
factors are efficiently obtained in closed form, using compact
formulas. Our technique is illustrated by a substrate integrated
waveguide interconnect with CPW transitions.
