Resumen
Descripción
A computationally efficient linear output space
mapping technique is proposed in this work to optimize
single-layer SIW interconnects with microstrip transitions
using full-wave electromagnetic simulators. The initial design
of the SIW structure is obtained from empirical equations. A
very low-resolution EM model with solid walls (grooves) and
lossless metals is exploited as an efficient surrogate for direct
EM optimization. The surrogate model is enhanced by
developing an output linear mapping over a large region of
interest, centered at the optimal coarse model solution. The
enhanced interpolated surrogate is re-optimized to find the
optimal transition. An excellent match is obtained between
the original fine model and the enhanced surrogate model at
the optimal solution found. The proposed technique is
illustrated by designing a 10-50 GHz SIW interconnect with
microstrip transitions on a standard FR4-based substrate.
