SUMMARY A technique for accurate modeling of microwave components is presented. Our methodology exploits a recently introduced shape‐preserving response prediction (SPRP) technology, which is adopted here to work directly with electromagnetic simulation data of the device under consideration. Unlike in original SPRP, no low‐fidelity model is used, which simplifies implementation and makes our method applicable for a variety of microwave structures. SPRP allows us to create models at a low computational cost of a few electromagnetic simulations, which is convenient when solving various design tasks such as parametric optimization. As demonstrated using several test structures including microstrip filters and a planar antenna, the modeling accuracy is competitive to standard approximation techniques. Application examples for design optimization and statistical analysis are also provided. Copyright © 2011 John Wiley & Sons, Ltd.
