Resumen
Descripción
Surrogate modeling using a polynomial
approximation of a coarse model of a Substrate
Integrated Waveguide (SIW) with microstrip
transitions is presented in this paper. The surrogate
modeling process is realized considering different base
points distributions, as well as different sizes for the
region of interest in order to evaluate their impact on
the corresponding surrogate modeling accuracy. The
polynomial approximation is a low-order function of
the design variables and it is used to approximate
electromagnetic responses of the SIW interconnect in a
region of interest around the selected central base
point. The surrogate modeling process is implemented
in Matlab, while the electromagnetic responses of the
SIW are obtained using a low-resolution EM model
implemented in CST Microwave Studio to speed up the
modeling process.
