Abstract :
In this paper, we present a maximally flat quadratic interpolation (MFQI) enhanced input space mapping modeling technique. The linear input mapping is enhanced by an MFQI input correction term to compensate for the nonlinear mismatch between the fine model and its surrogate within the region of interest. We demonstrate the accuracy improvement using a microstrip bend example.
